Abstract
A method and computer program product for use in a control system. The controller includes a first gain element configured to provide a first predetermined gain to an output error signal describing an error in the output of the control system; a compensator including a control loop including a storage element, the control loop receiving the output error signal, a second gain element configured to provide a second predetermined gain to the output of the control loop, and a detector configured to modify the contents of the storage element according to a predetermined adjustment value when a minimum predetermined excursion occurs in the output error signal; and a combiner configured to combine the outputs of the first and second gain elements to produce an output control signal for the control system.
