H ∞ Guaranteed Cost Fault-Tolerant Control of Double-Fault Networked Control Systems: Piecewise Delay Method

الملخص EN

The term double-fault networked control system means that sensor faults and actuator faults may occur simultaneously in networked control systems.

The issues of modelling and an H∞ guaranteed cost fault-tolerant control in a piecewise delay method for double-fault networked control systems are investigated.

The time-varying properties of sensor faults and actuator faults are modelled as two time-varying and bounded parameters.

Based on the linear matrix inequality (LMI) approach, an H∞ guaranteed cost fault-tolerant controller in a piecewise delay method is proposed to guarantee the reliability and stability for the double-fault networked control systems.

Simulations are included to demonstrate the theoretical results of the proposed method.
