• Generation of Conditional Densities in Nonlinear Filtering for Infinite-Dimensional Systems

Publication Year: 2018, Page(s):1868 - 1882
| | PDF (407 KB) | HTML

Consider a signal process that takes values in an infinite-dimensional space and assume that this process is observed through a nonlinear diffusion process. In the nonlinear filtering theory literature, recursive expressions for such problems in the form of conditional expectations and, consequently, measure-valued stochastic partial differential equations on the underlying infinite-dimensional sp...

• Learning Model Predictive Control for Iterative Tasks. A Data-Driven Control Framework

Publication Year: 2018, Page(s):1883 - 1896
| | PDF (1058 KB) | HTML

A learning model predictive controller for iterative tasks is presented. The controller is reference-free and is able to improve its performance by learning from previous iterations. A safe set and a terminal cost function are used in order to guarantee recursive feasibility and nondecreasing performance at each iteration. This paper presents the control design approach, and shows how to recursive... View full abstract»

• Bisimulation Equivalence of Discrete-Time Stochastic Linear Control Systems

Publication Year: 2018, Page(s):1897 - 1912
| | PDF (515 KB) | HTML

In this paper, we propose a definition of equivalence via stochastic bisimulation for the class of discrete-time stochastic linear control systems with possibly degenerate normally distributed disturbances. The notion is inspired by the notion of probabilistic bisimulation for probabilistic chains. Geometric necessary and sufficient conditions for checking this notion are derived. Model reduction ...

• Centralized Versus Decentralized Optimization of Distributed Stochastic Differential Decision Systems With Different Information Structures—Part II: Applications

Publication Year: 2018, Page(s):1913 - 1928
| | PDF (450 KB) | HTML

In this second part of the two-part paper, a stochastic maximum principle, conditional Hamiltonians, and the coupled backward-forward stochastic differential equations of the first part [1] are employed to derive decentralized team optimal strategies for distributed decision systems with different information structures. Examples of such team problems are presented in nonlinear and linear quadrati... View full abstract»

• Invariance With Dynamic Multipliers

Publication Year: 2018, Page(s):1929 - 1942
| | PDF (606 KB) | HTML

This paper focusses on the robust or absolute stability analysis of feedback interconnections consisting of a linear time-invariant system and an uncertain linear or nonlinear component. Building on the framework of integral quadratic constraints, we establish a novel local stability result using general dynamic multipliers that enables the verification of hard time-domain state and output constra...

• Backstepping PDE Design: A Convex Optimization Approach

Publication Year: 2018, Page(s):1943 - 1958
Cited by:  Papers (1)
| | PDF (965 KB) | HTML

Backstepping design for boundary linear partial differential equation (PDE) is formulated as a convex optimization problem. Some classes of parabolic PDEs and a first-order hyperbolic PDE are studied, with particular attention to nonstrict feedback structures. Based on the compactness of the Volterra- and Fredholm-type operators involved, their Kernels are approximated via polynomial functions. Th... View full abstract»

• Pattern Formation Via Eigenstructure Assignment: General Theory and Multi-Agent Application

Publication Year: 2018, Page(s):1959 - 1972
| | PDF (1167 KB) | HTML

Complex dynamical systems often exhibit formation of a pattern in observed variables in the steady state. An important special case is when the system consists of multiple subsystems (or “agents”) subjected to local interactions to reach consensus or an arbitrary pattern specified by their relative positioning in the state space. This paper formulates a general pattern formation prob... View full abstract»

• Prediction-Correction Interior-Point Method for Time-Varying Convex Optimization

Publication Year: 2018, Page(s):1973 - 1986
| | PDF (948 KB) | HTML

In this paper, we develop an interior-point method for solving a class of convex optimization problems with time-varying objective and constraint functions. Using log-barrier penalty functions, we propose a continuous-time dynamical system for tracking the (time-varying) optimal solution with an asymptotically vanishing error. This dynamical system is composed of two terms: a correction term consi... View full abstract»

• Liveness-Enforcing Supervision in AMS-Oriented HAMGs: An Approach Based on New Characterization of Siphons Using Petri Nets

Publication Year: 2018, Page(s):1987 - 2002
| | PDF (779 KB) | HTML

In the context of automated manufacturing systems, flexibility and synchronization are two main representative formations. Supervisory control techniques for flexibility have gained increasing attention, but those for synchronization operations have received little notice. Based on their comparison, our work makes threefold contributions. First, we propose a novel characterization of siphons, i.e.... View full abstract»

• Reachability Analysis for Solvable Dynamical Systems

Publication Year: 2018, Page(s):2003 - 2018
| | PDF (913 KB) | HTML

The reachability problem is one of the most important issues in the verification of hybrid systems. But unfortunately the reachable sets for most of hybrid systems are not computable. In the literature, only some special families of linear vector fields are proved with decidable reachability problem, let alone nonlinear ones. In this paper, we investigate the reachability problem of nonlinear vect... View full abstract»

• An Incentive-Based Online Optimization Framework for Distribution Grids

This paper formulates a time-varying social-welfare maximization problem for distribution grids with distributed energy resources (DERs) and develops online distributed algorithms to identify (and track) its solutions. In the considered setting, network operator and DER-owners pursue given operational and economic objectives, while concurrently ensuring that voltages are within prescribed limits. ...

• Range-Only-Based Three-Dimensional Circumnavigation of Multiple Moving Targets by a Nonholonomic Mobile Robot

Publication Year: 2018, Page(s):2032 - 2045
| | PDF (930 KB) | HTML

A nonholonomic constant speed underactuated robot with a bounded control range travels in three dimensions. A group of targets unpredictably moves in all three dimensions. The robot measures only the distances to the targets and also has access to a certain spatial direction and its own coordinate (termed “altitude”) along it. We present a new navigation law that drives the robot to ... View full abstract»

• Regularization of Chattering Phenomena via Bounded Variation Controls

Publication Year: 2018, Page(s):2046 - 2060
| | PDF (627 KB) | HTML

In the control theory, the term chattering is used to refer to fast oscillations of controls, such as an infinite number of switchings over a finite time interval. In this paper, we focus on three typical instances of chattering: the Fuller phenomenon, referring to situations where an optimal control features an accumulation of switchings in finite time; the Robbins phenomenon, concerning optimal ...

• Observability Through a Matrix-Weighted Graph

Publication Year: 2018, Page(s):2061 - 2074
| | PDF (676 KB) | HTML

Observability of an array of identical linear time-invariant systems with incommensurable output matrices is studied, where an array is called observable when identically zero relative outputs imply synchronized solutions for the individual systems. It is shown that the observability of an array is equivalent to the connectivity of its interconnection graph, whose edges are assigned matrix weights... View full abstract»

• Hierarchical Robust Performance Analysis of Uncertain Large Scale Systems

Publication Year: 2018, Page(s):2075 - 2090
| | PDF (1031 KB) | HTML

In this paper, the problem of robust performance analysis of interconnected uncertain systems with hierarchical structure is investigated. The computational load associated with such problems does not allow a direct application of robustness analysis usual tools. To overcome this difficulty, we exploit the hierarchical structure of the problem and propose an algorithm to perform robustness analysi... View full abstract»

• Growing Linear Dynamical Networks Endowed by Spectral Systemic Performance Measures

Publication Year: 2018, Page(s):2091 - 2106
Cited by:  Papers (1)
| | PDF (1097 KB) | HTML

We propose an axiomatic approach for design and performance analysis of noisy linear consensus networks by introducing a notion of systemic performance measure. This class of measures are spectral functions of Laplacian eigenvalues of the network that are monotone, convex, and orthogonally invariant with respect to the Laplacian matrix of the network. It is shown that several existing gold-standar... View full abstract»

• Feedback Stabilization of Switched Linear Systems With Unknown Disturbances Under Data-Rate Constraints

Publication Year: 2018, Page(s):2107 - 2122
| | PDF (792 KB) | HTML

We study the problem of stabilizing a switched linear system with a completely unknown disturbance using sampled and quantized state feedback. The switching is assumed to be slow enough in the sense of combined dwell time and average dwell time, each individual mode is assumed to be stabilizable, and the data rate is assumed to be large enough but finite. By extending the approach of reachable-set... View full abstract»

• Efficient Quadratic Penalization Through the Partial Minimization Technique

Publication Year: 2018, Page(s):2131 - 2138
| | PDF (851 KB) | HTML

Common computational problems, such as parameter estimation in dynamic models and partial differential equation (PDE)-constrained optimization, require data fitting over a set of auxiliary parameters subject to physical constraints over an underlying state. Naive quadratically penalized formulations, commonly used in practice, suffer from inherent ill-conditioning. We show that surprisingly the pa... View full abstract»

• Robust Controllability of Switched Asynchronous Sequential Machines

Publication Year: 2018, Page(s):2139 - 2144
| | PDF (310 KB) | HTML

This paper investigates robust controllability of switched asynchronous sequential machines (ASMs) with permanent faults. A switched ASM can change its mode through a number of submachines in an asynchronous mechanism. The main objective is to develop a condition for the corrective control scheme that makes the closed-loop system robust against permanent faults while matching its stable-state beha...

In this paper, we study the simultaneous stability problem of a finite number of locally interconnected linear subsystems under practical constraints, including asynchronous and aperiodic sampling, time-varying delays, and measurement errors. We establish a new Lyapunov-based stability result for such a decentralized system. This system has a particular simple structure of interconnections, but it... View full abstract»
