Model Predictive Event-Triggered Non-Fragile Fault-Tolerant Control for IT2 T-S Fuzzy Systems with Static Output Feedback

This paper presents an innovative event-triggered non-fragile fault-tolerant control approach towards the interval type-2 (IT2) Takagi-Sugeno (T-S) fuzzy systems subject to bounded disturbances and actuator faults based on model predictive control (MPC) strategy. The proposed fault-tolerant control method integrates both an event-triggered strategy to alleviate the transmission pressure and energy consumption of the network and a non-fragile controller design strategy to remain resilient to potential gain perturbations. Quadratic bounded (QB) technology is used to design static output feedback controllers. Moreover, the proposed method guarantees recursive feasibility and quadratical stability of closed-loop dynamics. The validity of method is verified through an example.
