相关介绍: | Abstract In this talk, we will discuss the problem of fault tolerant control and performance optimization for singular systems subject to both nonlinear perturbation and actuator saturation. Two methods, namely, saturation avoidance method and saturation allowance method are proposed to address this issue. Some conditions for the existence of controllers are derived which guarantees the regularity, impulse-free and stability of the closed-loop system under all possible faults. In addition, some optimization problems are also formulated to determine the largest contractively invariant set. The L2\L∞ performance of the closed-loop system can be naturally obtained based on the above results. For the adaptive controller, the failure effects on the system can be compensated by estimating the fault and updating the design parameter matrices online.
