Synchronization design of H∞ filter and controller for discrete switched LPV systems with distributed delays based on event-triggered mechanism.

In order to save the United network resources and improve the utilization rate of network resources, for discrete switched linear parameter varying (LPV) systems with distributed delays, an event-triggering mechanism with independent filter and controller is established, and the Her and controller are designed synchronously. The Lyapunov functional with low conservative time-delay correlation is selected, and the average dwell time (ADT) method is used to obtain the sufficient conditions for the exponential stability of the filter error system and the control system and for meeting the performance index. The linear matrix inequality (LMI) technique is used to solve the parameters of the filter and controller. The design scheme is verified by simulation. The results show that the synchronization designs scheme of filter and controller makes the system stabilize the original system state under the condition of incomplete measurably, improve the disturbance rejection ability of the system, and effectively reduce the occupation of network resources. The switched LPV model of aeroengine is used for numerical simulation to verify the effectiveness of the synchronous design scheme of filter and controller. [ABSTRACT FROM AUTHOR]
