Saturation-based switching anti-windup design for linear systems with nested input saturation

摘要: This paper proposes a saturation-based switching anti-windup design for the enlargement of domain attraction linear system subject to nested saturation. A nestedly saturated feedback is expressed as combination set auxiliary feedbacks, which form convex hull where resides. feedbacks then partitioned into several subsets. The in each these subsets sub-hull original hull. When value falls sub-hull, it can be subset all that sub-hull. separate gain designed by using common quadratic Lyapunov function and implemented when this Simulation results indicate such has ability significantly enlarge closed-loop system.
