Abstract
An integral plus proportional control system responding to more than one variable controls a single actuator wherein the integral gain is selected in accordance with the error of that variable which is being controlled to compensate for varying process dynamics. An error selector serves to discriminate the error signal which is being controlled and synchronously selects the gain of the integrator.
