GAIN SCHEDULLED CONTROLLERS FOR DYNAMIC SYSTEMS WITH SECTOR NONLINEARITIES

摘要

A gain scheduling approach to the control of dynamic systems with sector nonlinearities is givea The gain scheduled controller proposed uses the system state to switch linear robust controllers in subsets of the system domain of attraction around the operating point. The procedure guarantees the stability of the feedback closed-loop system and reduces the amount of conservatism that results when a large region of attraction around the operating point is considered. In addiction, the problem of guaranteed transition between operating points by using a pre-specified path in the state space for the system operating points is considered.
