Abstract

This paper designs switched controllers for a class of linear parameter varying (LPV) systems with inexactly measured parameters. H_∞ performance problem is solved, and a switched LPV controller is designed. By using the multiple Lyapunov functions method, Linear Matrix Inequality (LMI) conditions are proposed, and a switching law is designed based on the hysteresis method. An active magnetic bearing (AMB) example shows effectiveness of proposed method.
