Control systems with actuator saturation
WebMar 1, 2010 · Nearly all physical systems are subject to saturation constraints, such as actuator saturation and/or sensor saturation. It is known that actuator saturation may have adverse effects on the performance and stability of a closed-loop system if the controller is designed without considering this kind of nonlinearity. WebMar 23, 2024 · This paper considers a non-fragile guaranteed cost control problem for a class of nonlinear switched systems with actuator saturation. For nonlinear switched systems, we derive some sufficient conditions to satisfy simultaneously the stabilization and the performance index of guaranteed cost control.
