HARMONICS ATTENUATOR USING COMBINATION FEEDBACK CONTROLLER

摘要

A harmonics attenuator employing a combination controller that incorporates features of a classic controller and a state space controller to function as a hybrid controller unit, arranged in a manner that the two controllers compliment each other and improve overall performance of the system The PID portion of the classic controller, which regulates the steady state error, is coupled with a state space controller, which generates a transient error correction that is fed to a PWM signal generator
