Load transient response improvement based on PID control

In this study, a PID controller with the proposed control strategy is presented, which is used to improve the load transient response. During the load transient period, the parameters of the proposed controller are on-line adjusted and make the controller design easy. As compared with the traditional PID control, the proposed control strategy does not need additional hardware circuits. In addition, the corresponding calculation flow chart is varied as minimum as possible, such that the parameters of the PID controller is of easiness and generality.
