Event-triggered Observer-based Robust H∞ Fault-tolerant Control for Markov Jumping NCSs
Abstract
For network control systems (NCSs) with parameter uncertainties, packet loss and time-delays, the design for the observer and robust H∞ fault-tolerant controller is discussed with the event-triggered mechanism. The random Markov jumping system is used to describe the NCSs with faults. In order to reduce the frequency of data transmission and save network channel resources, the discrete event-triggered mechanism is utilized, which allows the NCS to transmit the signal when the trigger condition is met only. Under this mechanism the system states are estimated by the observer provided, while a robust fault-tolerant controller is designed for actuator failures, so that the NCSs can remain stable in the event of failures. Finally, the proposed method is verified by simulation, the respective results showing its validity and feasibility.
