Robust Exponential H∞ Fault Tolerant Control for Sampled-Data Control Systems With Actuator Failure: A Switched System Method

Blog Article

In this paper, the robust exponential $H_{infty }$ fault tolerant control problem is investigated, which is concerned with uncertainties, disturbances and actuator BABYDOLL failures.Determined by whether the actuator fails or not, the continuous-time system is remodeled as a switched system.Then a sampled-data controller is designed.Through Lyapunov functional theory and the admissible edge-dependent average dwell time method, some sufficient conditions are derived to ensure that the closed-loop system is robustly exponentially stable with exponential $H_{infty }$ performance.

The corresponding controller Marble Dining Table gains can also be obtained via linear matrix inequalities (LMIs).Finally, two examples are presented to verify the validity of the relevant results.
