Reliable Stabilization and H∞ Control for Switched Systems with Faulty Actuators: An Average Dwell Time Approach
نویسندگان
چکیده
This paper deals with the issues of observer-based reliable stabilization and H∞ control for a class of continuoustime switched Lipschitz nonlinear systems in the sense that actuators suffer a “destabilizing failure”. When the never-faulty actuators cannot stabilize the corresponding system, the closedloop switched systems can still be exponentially stable based on the average dwell time scheme. Under the condition requiring that activation time ratio between stabilizable subsystems and unstabilizable ones is not less than a specified constant, sufficient condition is derived for the switched systems to be exponentially stabilizable for all admissible actuator failures via switching and associated observer-based feedback controllers. The result is also extended to solve the observer-based reliable H∞ control problem.

Local stabilization for a class of nonlinear impulsive switched system with non-vanishing uncertainties under a norm-bounded control input
Stability and stabilization of impulsive switched system have been considered in recent decades, but there are some issues that are not yet fully addressed such as actuator saturation. This paper deals with expo-nential stabilization for a class of nonlinear impulsive switched systems with different types of non-vanishing uncertainties under the norm-bounded control input. Due to the constraine...
متن کاملDesign of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملA new switching strategy for exponential stabilization of uncertain discrete-time switched linear systems in guaranteed cost control problem
Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...
متن کاملAverage Dwell-time Method to Stabilization and L2-gain Analysis for Uncertain Switched Nonlinear Systems
This paper is concerned with the problem of stabilization and L2-gain analysis for a class of switched nonlinear systems with norm-bounded time-varying uncertainties. A system in this class is composed of two parts: a uncertain linear switched part and a nonlinear part, which are also switched systems. When all the subsystem are stabilizable and have a L2-gain, the switched feedback control law...
متن کاملA new approach based on state conversion to stability analysis and control design of switched nonlinear cascade systems
In this paper, the problems of control and stabilization of switched nonlinear cascade systems is investigated. The so called simultaneous domination limitation (SDL) is introduced in previous works to assure the existence of a common quadratic Lyapunov function (CQLF) for switched nonlinear cascade systems. According to this idea, if all subsystems of a switched system satisfy the SDL, a CQLF ...
