Control systems with actuator saturation
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. WebMar 1, 2010 · The main contributions in this paper are: (1) The designed saturation avoidance feedback controllers have relatively small actuator capacities compared with the high gain ones; (2) Our method can deal with singular systems with actuator saturation and nonlinear perturbation while the existing results cannot be implemented directly; …
