ABSTRACT:
An apparatus and method for eliminating integrator windup in control systems having a control input, a feedback signal and an actuator that can saturate in response to dynamic non linearities such as slew rate limits. The apparatus of the invention is comprised of circuitry that determines the rate of change of the output of the integrator and compares it to predetermined maximum allowable rates of change. If these maximum allowable rates of change have been exceeded, the comparator circuitry generates a compensation error signal which when combined with normal error signal integrated by the compensator tends to reduce the rate of change on the output of the integrator.
