Abstract
Controller complexity reduction is an issue in many applications. The key objectives of controller complexity reduction is to obtain a reduced order controller which preserves the closed-loop properties of the nominal closed-loop system (stability, robustness, performance). The techniques for controller complexity (order) reduction which will be presented are based on the estimation in closed-loop of a reduced order controller. Methods for the validation of the estimated reduced order controllers are also presented. The use of these techniques is illustrated by an example in robust control design of an active vibration control system.
