This work provides a general framework for the analysis and synthesis of a class of relative sensing networks (RSNs) in the context of its H2 and H performance. We consider RSNs with homogeneous and heterogeneous agent dynamics. In both cases, explicit graph theoretic expressions and bounds for the H2 and H per... View full abstract»

• A Geometric Approach to Variance Analysis in System Identification

Publication Year: 2011, Page(s):983 - 997

This paper addresses the problem of quantifying the model error (“variance-error”) in estimates of dynamic systems. It is shown that, under very general conditions, the asymptotic (in data length) covariance of an estimated system property (represented by a smooth function of estimated system parameters) can be interpreted in terms of an orthogonal projection of a certain function, a...

• A Switched State Feedback Law for the Stabilization of LTI Systems

Publication Year: 2011, Page(s):998 - 1013
Cited by:  Papers (10)
| | PDF (563 KB) | HTML

Inspired by prior work in the design of switched feedback controllers for second-order systems, we develop a switched state feedback control law for the stabilization of linear time-invariant (LTI) systems of arbitrary dimension. The control law operates by switching between two static gain vectors in such a way that the state trajectory is driven onto a stable n-1 dimensional hyperplane (where View full abstract»

• Control Over Noisy Forward and Reverse Channels

Publication Year: 2011, Page(s):1014 - 1029
Cited by:  Papers (24)
| | PDF (485 KB) | HTML

We consider the problem of remotely controlling a continuous-time linear time-invariant system driven by Brownian motion process, when communication takes place over noisy memoryless discrete- or continuous-alphabet channels. What makes this class of remote control problems different from most of the previously studied models is the presence of noise in both the forward channel (connecting sensors... View full abstract»

| | PDF (667 KB) | HTML

Low-gain feedback has found several applications in constrained control, robust control, and nonlinear control. In this paper, we first generalize the existing low-gain design methods by introducing the notion of L-vanishment and by providing a full characterization of feedback gains that achieve such a property. We observe that L low-gain feedba... View full abstract»

• Symmetry-Based Observers for Some Water-Tank Problems

Publication Year: 2011, Page(s):1046 - 1058
Cited by:  Papers (2)
| | PDF (785 KB) | HTML

In this paper, we consider a tank containing fluid and we want to estimate the horizontal currents when the fluid surface height is measured. The fluid motion is described by shallow water equations in two horizontal dimensions. We build a simple nonlinear observer which takes advantage of the symmetries of fluid dynamics laws. As a result its structure is based on convolutions with smooth isotrop... View full abstract»

| | PDF (890 KB) | HTML

In this paper, a unified framework is proposed to study the exponential stability of discrete-time switched linear systems and, more generally, the exponential growth rates of their trajectories under three types of switching rules: arbitrary switching, optimal switching, and random switching. It is shown that the maximum exponential growth rates of system trajectories over all initial states unde... View full abstract»

• Entrainment to Natural Oscillations via Uncoupled Central Pattern Generators

Publication Year: 2011, Page(s):1075 - 1089
Cited by:  Papers (15)
| | PDF (532 KB) | HTML

Mechanical systems can often be controlled efficiently by exploiting a resonance. An optimal trajectory minimizing an energy cost function is found at (or near) a natural mode of oscillation. Motivated by this fact, we consider the natural entrainment problem: the design of nonlinear feedback controllers for linear mechanical systems to achieve a prescribed mode of natural oscillation for the clos...

For a state-constrained control system described by a differential inclusion and a single functional inequality state constraint, it is known that, under an “inward pointing condition”, the W1,1 distance of an arbitrary state trajectory to the set of state trajectories, which have the same left endpoint and which satisfy the state constraint, is linearly related to ...

| | PDF (486 KB) | HTML

We formulate the Lebesgue-sampling-based optimal control problem. We show that the problem can be solved by the time aggregation approach in Markov decision processes (MDP) theory. Policy-iteration-based and reinforcement-learning-based methods are developed for the optimal policies. Both analytical solutions and sample-path-based algorithms are given. Compared to the periodic-sampling scheme, the... View full abstract»

• The Achievable Dynamics via Control by Interconnection

Publication Year: 2011, Page(s):1110 - 1117

| | PDF (355 KB) | HTML

We consider the problem of finding a controller such that, when interconnected to the plant, we obtain a system that is equivalent to a desired system. Here, “equivalence” is formalized as “bisimilarity.” We give necessary and sufficient conditions for the existence of such a controller. The systems we consider are linear input-state-output systems. A comparison is made... View full abstract»

This technical note is concerned with stability analysis and stabilization of Itô stochastic systems with Markovian switching. A couple of eigenvalue sets for some positive operator associated with the stochastic system under study are defined to characterize its stability in the mean square sense. Properties for these eigenvalue sets are established based on which we show that the spectra... View full abstract»

We prove a general result of collision-avoiding flocking. The underlying model allows several forms of coupling forces and the main result ensures flocking provided the initial state of the population does not show simultaneously very different velocities, very spread positions or very close agents.

This technical note addresses the stabilization of switching discrete-time linear systems with control inputs under arbitrary switching. A sufficient condition for the uniform global exponential stability (UGES) of such systems is the existence of a common quadratic Lyapunov function (CQLF) for the component subsystems, which is ensured when the closed-loop component subsystem matrices are stable ...

This works considers the problem of control of linear systems with input constraints. The notion of control Lyapunov functions (CLFs) is first generalized and relaxed to define a constrained control Lyapunov function (CCLF) and a constructive procedure for CCLF is subsequently presented.

In this note, we demonstrate the use of a control oriented notion of finite state input/output approximation to synthesize correct-by-design controllers for hybrid plants under sensor limitations. Specifically, we consider the problem of designing stabilizing switching controllers for a pair of unstable homogeneous second order systems with binary output feedback. In addition to yielding a determi... View full abstract»

In this technical note, we present a novel synchronization protocol to synchronize a network of controlled discrete-time double integrators which are nonidentical, with unknown model parameters and subject to additive measurement and process noise. This framework is motivated by the typical problem of synchronizing a network of clocks whose speeds are nonidentical and are subject to variations. Th... View full abstract»

• Adaptive Redesign of Nonlinear Observers

Publication Year: 2011, Page(s):1152 - 1157

| | PDF (430 KB) | HTML

To estimate unmeasured states in dynamical systems with parametric uncertainties one can use adaptive observers. In this technical note a new method for adaptive redesign of reduced order observers for nonlinear systems is presented. The redesign makes the observer robust as it guarantees that the state estimation error converges to zero in the presence of parametric uncertainties. To enable param... View full abstract»

• A Finite-Memory Algorithm for Batch Means Estimators in Simulation Output Analysis

Publication Year: 2011, Page(s):1157 - 1162
Cited by:  Papers (2)
| | PDF (708 KB) | HTML

A classic problem of stochastic simulation is estimating the variance of point estimators, the prototype estimator being the sample mean from a steady-state autocorrelated process. The traditional batch means (BM) estimator requires knowledge of the sample size a priori. This paper proposes an algorithm to implement certain BM estimators without knowing the sample size in advance. The proposed alg... View full abstract»

Real-time knowledge of the slip angle in a vehicle is useful in many active vehicle safety applications, including yaw stability control, rollover prevention, and lane departure avoidance. Sensors that can directly measure slip angle are too expensive for ordinary automotive applications. This technical note develops a new nonlinear observer design technique for estimation of slip angle using inex... View full abstract»

The coordinated path following problem, steering a fleet of unicycles along a path while achieving a desired inter-vehicle formation, is investigated. The path is a paved road in the world or a marked curve on the floor of work area, for which each vehicle can measure the distance to the path and the heading error as well as the curvature of the path segment in its sensing range. Moreover, the veh... View full abstract»

• Production and Inventory Rationing in a Make-to-Stock System With a Failure-Prone Machine and Lost Sales

Publication Year: 2011, Page(s):1176 - 1180

| | PDF (359 KB) | HTML

We consider production and inventory rationing of a product to fulfill multiple demand classes in a make-to-stock production system with a failure-prone machine. Demand that cannot be satisfied immediately is lost and incurs a lost sales cost, which differs from class to class. We find that the optimal control policies under both the expected total discounted cost criterion and the average cost cr... View full abstract»
