<正>The importance of taking actuator saturation into consideration in the design of practical control systems has been well recognized. Two facts are clear. Actuator saturation reduces the anticipated closed-loop performance of the closed-loop system,and in a severe situation, may cause loss of closedloop stability. A saturation avoidance control design incurs conservativeness in achieving closedloop performance. The analysis and design of control systems in the presence of actuator saturation
