| |PDF (698 KB) | HTML

In this paper, a novel discrete-time implementation of sliding-mode control systems is proposed, which fully exploits the multivaluedness of the dynamics on the sliding surface. It is shown to guarantee a smooth stabilization on the discrete sliding surface in the disturbance-free case, hence avoiding the chattering effects due to the time-discretization. In addition, when a disturbance acts on th... View full abstract»

• ### On the Relationship Between the Enforced Convergence Criterion and the Asymptotically Optimal Laguerre Pole

Publication Year: 2012, Page(s):1102 - 1109
Cited by:  Papers (4)
| |PDF (586 KB) | HTML

When approximating dynamic systems with Laguerre basis functions (LBFs) it is important to tune the Laguerre pole such that the expansion can be both parsimonious and accurate. Expressing the sum of squared errors (SSE) as a function of the Laguerre pole leads to an objective function that has many local minima and therefore cannot be optimized directly. Two alternative methods have been proposed ... View full abstract»

• ### Optimal Supervisory Control of Probabilistic Discrete Event Systems

| |PDF (4289 KB) | HTML

Probabilistic discrete event systems (PDES) are modeled as generators of probabilistic languages and the supervisors employed are a probabilistic generalization of deterministic supervisors used in standard supervisory control theory. In the case when there exists no probabilistic supervisor such that the behavior of a plant under control exactly matches the probabilistic language given as the req... View full abstract»

• ### On Saturation, Discontinuities, and Delays, in iISS and ISS Feedback Control Redesign

Publication Year: 2012, Page(s):1125 - 1140
Cited by:  Papers (17)
| |PDF (519 KB) | HTML

This paper addresses input-to-state stability (ISS) and integral ISS (iISS) redesign to enhance robustness of feedback control systems in the face of actuator disturbances. The idea of the redesign is to modify control laws available for disturbance-free systems a priori in order to achieve robustness against the disturbance. In practice, control system design often encounters time-delays, discont... View full abstract»

• ### Nonlinear Stabilization Under Sampled and Delayed Measurements, and With Inputs Subject to Delay and Zero-Order Hold

Publication Year: 2012, Page(s):1141 - 1154
Cited by:  Papers (111)
| |PDF (596 KB) | HTML

Sampling arises simultaneously with input and output delays in networked control systems. When the delay is left uncompensated, the sampling period is generally required to be sufficiently small, the delay sufficiently short, and, for nonlinear systems, only semiglobal practical stability is generally achieved. For example, global stabilization of strict-feedforward systems under sampled measureme... View full abstract»

• ### Opacity-Enforcing Supervisory Strategies via State Estimator Constructions

Publication Year: 2012, Page(s):1155 - 1165

State-based notions of opacity, such as initial-state opacity and infinite-step opacity, emerge as key properties in numerous security applications of discrete event systems. We consider systems that are modeled as partially observed nondeterministic finite automata and tackle the problem of constructing a minimally restrictive opacity-enforcing supervisor (MOES), which limits the system's behavio...

Path-planning problems are fundamental in many applications, such as transportation, artificial intelligence, control of autonomous vehicles, and many more. In this paper, we consider the deterministic path-planning problem, equivalently, the single-pair shortest path problem on a given grid-like graph structure. Current commonly used algorithms in this area include the A* algorithm, Dijkstra's al... View full abstract»

• ### Max Weight Learning Algorithms for Scheduling in Unknown Environments

Publication Year: 2012, Page(s):1179 - 1191
Cited by:  Papers (11)
| |PDF (700 KB) | HTML

We consider a discrete time queueing system where a controller makes a 2-stage decision every slot. The decision at the first stage reveals a hidden source of randomness with a control-dependent (but unknown) probability distribution. The decision at the second stage generates an attribute vector that depends on this revealed randomness. The goal is to stabilize all queues and optimize a utility f... View full abstract»

• ### Nash Equilibrium Seeking in Noncooperative Games

Publication Year: 2012, Page(s):1192 - 1207
Cited by:  Papers (62)
| |PDF (1117 KB) | HTML

We introduce a non-model based approach for locally stable convergence to Nash equilibria in static, noncooperative games with N players. In classical game theory algorithms, each player employs the knowledge of the functional form of his payoff and the knowledge of the other players' actions, whereas in the proposed algorithm, the players need to measure only their own payoff values. This ... View full abstract»

In this paper we consider the class of discrete-time switched systems switching between p autonomous positive subsystems. First, sufficient conditions for testing stability, based on the existence of special classes of common Lyapunov functions, are investigated, and these conditions are mutually related, thus proving that if a linear copositive common Lyapunov function can be found, then a...

| |PDF (656 KB) | HTML

Timed event graphs (TEGs) and timed weighted event graphs (TWEGs), which have multiple arc cardinalities, have been widely used for automated production systems such as robotic work cells or embedded systems. TWEGs are useful for modeling batch flows of entities such as batch arrivals or processing of jobs. Periodic schedules, that combine an explicit description of starting times and an easy impl...

| |PDF (332 KB) | HTML

The problem of checking blocking properties is studied for networks consisting of arbitrary numbers of finite-state discrete-event subsystems. The topology of the networks is that of a fully connected graph: any subsystem can potentially interact with any other. Two types of blocking are studied: component blocking, whereby a subsystem is potentially prevented from entering its set of marker state... View full abstract»

This technical note concerns robust stability analysis of discrete-time linear-time-invariant (LTI) systems with varying time delays. The stability problem is tackled under the integral quadratic constraint (IQC) framework. The time-delay system in question is viewed as feedback interconnection of an LTI stable operator and the so-called “delay-difference” operator, for which IQC cha... View full abstract»

We consider remote state estimation over a packet-dropping network. A new suboptimal filter is derived by minimizing the mean squared estimation error. The estimator is designed by solving one deterministic Riccati equation. Convergence of the estimation error covariance and mean square stability of the estimator are proved under standard assumptions. It is shown that the new estimator has smaller... View full abstract»

We show that for a general class of distributed power control algorithms in wireless networks, if a feasible steady state power allocation exists, this is asymptotically stable for arbitrary gains and time varying heterogeneous delays. The analysis exploits certain contraction properties of the interference in such algorithms, and makes use of Lyapunov Razumikhin functions to address the infinite ... View full abstract»

The task of failure prognosis requires the prediction of impending failures. This technical note formulates and studies the problem of distributed prognosis of discrete event systems, where the local prognosers exchange their observations for the sake of arriving at a prognostic decision. The observations are exchanged over communication channels that introduce bounded delays. A property of joint-... View full abstract»

• ### Verification of Infinite-Step Opacity and Complexity Considerations

Publication Year: 2012, Page(s):1265 - 1269

| |PDF (196 KB) | HTML

We describe and analyze the complexity of verifying the notion of infinite-step opacity in systems that are modeled as non-deterministic finite automata with partial observation on their transitions. Specifically, a system is infinite-step opaque if the entrance of the system state, at any particular instant, to a set of secret states remains opaque (uncertain), for the length of the system operat...

In this technical note, we consider adaptive learning control problem for a class of nonlinear systems with periodic bounded disturbances. The bounds of the disturbance are unknown, and the minimum period T* of the disturbance can be written as T* = l* τ , with τ being a known constant and l* being an unknown integer. Our proposed adaptive controller consi... View full abstract»

| |PDF (441 KB) | HTML

Most existing methods for satellite attitude control assume that full knowledge of satellite attitude is available by algebraic manipulation of at least two vector measurements from attitude sensors such as Sun, Earth-horizon, Earth-magnetic or star tracker sensors. Kalman filtering is usually used when only one vector measurement is available, however, asymptotic stability of nonlinear and uncert... View full abstract»

We consider L∞-control of MIMO systems and address solvability of the problem over all finite dimensional LTI controllers: i.e., controllers whose transfer functions can be proper or improper. We show that improper controllers are easily dealt with using the behavioral approach, unlike the standard state-space/transfer-matrix methods, and argue that there are cases where a...

The problem of H∞ control of switched nonlinear systems in p-normal form is investigated in this technical note where the solvability of the H∞ control problem for individual subsystems is unnecessary. Using the generalized multiple Lyapunov functions method and the adding a power integrator technique, we design a switching law and construct... View full abstract»

Event-driven strategies for multi-agent systems are motivated by the future use of embedded microprocessors with limited resources that will gather information and actuate the individual agent controller updates. The controller updates considered here are event-driven, depending on the ratio of a certain measurement error with respect to the norm of a function of the state, and are applied to a fi...
