Abstract:
1. A control system for controlling a load, the controller comprising: a first summer adapted to receive a command signal and a feedback signal, the first summer adapted to generate a system error signal based upon the command signal and the feedback signal; a proportional gain component adapted to receive the system error signal, the proportional gain component adapted to generate a proportional gain output based upon the system error signal; a differentiator component adapted to receive one of an input signal based on the command signal or the feedback signal, the differentiator component adapted to generate a differentiated signal based upon the one of the input signal; a second summer adapted to receive the differentiated signal and the system error signal, the second summer adapted to generate a modified system error signal based upon the differentiated signal and the system error signal; an integral gain component adapted to receive the modified system error signal, the integral gain component adapted to generate an integrating output signal based upon the modified system error signal; and a third summer adapted to receive the proportional gain output and the integrating output signal, the third summer adapted to generate a second command signal, the second command signal being utilized to control the load and being based at least in part upon the proportional gain output and the integrating output signal.
