Abstract

Addresses the disturbance rejection problem in control systems with saturating actuators by using the method of stochastic linearization. The disturbance is assumed to be white noise and the performance measure considered is the output variance. Both analysis and synthesis problems are investigated. In the analysis part, a method is developed to predict disturbance rejection quality of a given control system. In the synthesis part, a systematic controller design method that achieves suboptimal disturbance rejection is presented
