DISCRETE-TIME LQG CONTROL WITH ACTUATOR FAILURE

Dariusz Horla, Andrzej Krolikowski

2011

Abstract

A discrete-time LQG control with actuator failure is considered. The control problem is analyzed in terms of algebraic Riccati equations. Computer simulations of two-input two-output system are given to illustrate the performance of the reliable LQG controller. An actuator saturation case is also included.
