Stability And Control For Switched Systems With Time-delay

In practical engineering systems,Switched control systems in complex systems are widely used.For example,in the field of aerospace,power system,and chemical industry.In addition,The time delay phenomenon,parameter uncertainty,actuator failure and external disturbance have a great influence on the stability and other control performance for practical engineering systems.Since the above reasons,this thesis discuss control and stability for the switching systems with time-delay based on the robust H? stability theory and control priciple,linear matrix inequality theory and Schur complement lemma.By establishing Lyapunoov-krasovskii functional,we illustrate our discussion as following aspects:(1)We studied robust H control problem is based on memory feedback controller for a class of the uncertain linear switched systems,we can obtain the controller with memory should be provided more freedom for robust stability analysis and synthesis for the system.(2)For a class of uncertain Lurie Singular switched systems.The reliable controller can guarantee the asymptotic stability and H? performance when the actuator in operation a fault happens.In addition,by designing the passive controller and the switching state feedback strategy,the asymptotic stability and passivity of the closed-loop system are obtained.(3)We analyzed robust H control problem is based on memory state feedback controller and output feedback controller for a class of the Lurie switched systems with time delay and Singular Lurie neutral switched systems with time-varying delay and distributed delay,and the asymptotic stability of these control systems are obtained.(4)The admissibility and attainability of a class of switched systems with distributed delay is analyzed by designing an adaptive controller.
