Abstract :
A method for designing integral control for a multivariable plant which handles actuator saturation in a stable and optimal way is presented. Multivariable techniques are used which attempt to get the best error reduction with a given control authority using only feedback information. Sufficient conditions for stability are given in the form of coupled Lyapunov equations. Results from an experimental rapid thermal processing system show that the operating range of the feedback controller was doubled over a controller which made no design provisions for actuator saturation
