Stability analysis for discrete-time switched linear singular systems: average dwell time approach
This paper investigates the stability analysis problem for discrete-time switched linear singular systems, in which the restrictions on singular matrices are removed. By identifying the state jumps at switching instants, and estimating the state norm of each subsystem consistently, an average dwell time approach is developed to solve the exponential stability problem. Numerical examples are given ...Show More
Extended Asynchronous Switching Control of Discrete-Time Switched Positive Linear Systems
2019 Chinese Control Conference (CCC)
Year: 2019 | Conference Paper |
An extended asynchronous switching control problem for a class of discrete-time switched positive linear systems is investigated in this paper. Different from the conventional asynchronous switching in the presence of only detection delay, the extended asynchronous switching stems from two aspects: detection delay and false alarm, which can better depict the practical situation in dynamic systems ...Show More

In this paper, the asymptotic stability of uncertain discrete switched systems with interval time-varying delay and linear fractional perturbations is achieved via switching signal design. Some linear matrix inequality (LMI) stability criteria are provided to design the switching signal by the proposed non-uniform delay-partitioning approach. Finally, some numerical examples are illustrated to sho...Show More

Both D-stability and finite L2-gain properties are studied for a class of uncertain discrete-time systems with time-varying network-induced delays. By using coordinate transform and delay partition, the D-stability and H∞ performance problems for such networked control systems (NCSs) are equivalently transferred into the corresponding problems for switching systems with arbitrary switching. Then, ...Show More

Model Approximation for Fuzzy Switched Systems With Stochastic Perturbation
In this paper, the model approximation problem is investigated for a Takagi-Sugeno fuzzy switched system with stochastic disturbance. For a high-order considered system, our attention is focused on the construction of a reduced-order model, which not only approximates the original system well with a Hankel-norm performance but translates it into a lower dimensional fuzzy switched system as well. B...Show More

In this technical note, the problem of stability for a class of slowly switched systems is investigated.

Nice reachability for planar bilinear control systems with applications to planar linear switched systems [corrected]
We consider planar bilinear control systems with measurable controls. We show that any point in the reachable set can be reached by a ldquonicerdquo control, specifically, a control that is a concatenation of a bang arc with either 1) a bang-bang control that is periodic after the third switch; or 2) a piecewise constant control with no more than two discontinuities. Under the additional assumptio...Show More

Yang Tian;Thierry Floquet;Lotfi Belkoura;Wilfrid Perruquetti
Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference
Year: 2009 | Conference Paper |
Cited by: Papers (9)
This paper aims at estimating the switching time for linear switched systems, i.e. the time instant when a sub-model is switched on while another one is switched off. Assuming that the state of the active sub-models is known, a distribution point of view is adopted to get a real-time estimation of these switching times. Real-time means that an explicit algorithm computes on-line these time instant...Show More

This paper analyzes the stability of a class of linear switched time-delay systems which contain unstable subsystems. Stability conditions are derived by applying the descriptor transformation and developing a new technique in the derivative of the Lyapunov functional, such that the effects of the mixed states are included. Consequently, the resulting delay dependent stability criteria are less co...Show More
This paper focuses on the fault-tolerant control (FTC) of networked control systems (NCSs) with packet dropouts using switched system approach. The basic idea is to model such NCSs as a discrete-time switched system. Thus, the FTC of such NCSs can be reduced to that of switched systems. Sufficient conditions are presented about the stabilization of NCSs. Stabilizing switched state/output feedback ...Show More

This paper addresses the problem of dynamic event-triggered asynchronous switching control approach with applications to AC-DC converter. In practice, switching of controllers is often lagged behind that of their corresponding subsystems owing to signal transmission, system detection and so on. Therefore, in this paper, we adopt asynchronous switching model to describe the system with asynchronous...Show More

This paper is concerned with the problem of stabilization for positive switched delay systems. A hysteresis switching law is designed to stabilize positive switched systems with a time delay. On one hand, such switching laws can eliminate the chattering resulting from state-dependent switching laws. On the other hand, a constant time delay may sometimes lead to the instability of positive switched...Show More

The state space approach is a common method for conducting reliability assessment of protective systems. However, as more factors affecting the reliability of protective relay are considered, the system Markov model is becoming more and more complex and its solving efficiency is decreasing. To avoid this, a method to simplify the Markov model of protective system is proposed in this paper. Based o...Show More

Characterization and Optimization of $l_{\infty}$ Gains of Linear Switched Systems
In this paper, we consider the l∞ gain characterizations of linear switched systems (LSS) and present various relevant results on their exact computation and optimization. Depending on the role of the switching sequence, we study two broad cases: first, when the switching sequence attempts to maximize, and second, when it attempts to minimize the l∞ gain. The first, named as worst-case throughout ...Show More
