ABSTRACT:
An override control system is provided in which the integral mode of the controllers not selected is forced to track the integral mode of the selected controller to prevent windup of the controllers not selected. Selection of the active controller is based only on the proportional mode for proportional-integral controllers. Selection of the active controller is based only on the proportional mode and the derivative mode for proportional-integral-derivative controllers.
