A control system may be switched between a Pseudo-Derivative Feedforward (PDFF) control manner and a Proportional Integral (PI) control manner. The control system includes a first operational element, a second operational element, a feedback proportion controller, an integrator, and a feedforward proportion controller. The first operational element and the second operational element are used to perform calculation of addition or subtraction on an input signal, a feedback signal, and a feedforward signal. The integrator generates an integral signal. The feedback proportion controller generates a feedback proportion signal according to a first feedback gain or a second feedback gain. The feedforward proportion controller generates a feedforward proportion signal according to a first feedforward gain or a second feedforward gain. The control system may be switched among the different control manners through selection among the first feedback gain, the second feedback gain, the first feedforward gain, and the second feedforward gain.
