ABSTRACT:
The invention provides a method for dynamically changing the loop bandwidth of a closed loop control system. At least one loop bandwidth parameter controls the loop bandwidth of the closed loop control system. An error signal reflecting the convergence status of the output signal of the closed loop control system is first detected. The at least one loop bandwidth parameter is then dynamically adjusted according to the error signal to change the loop bandwidth of the closed loop control system. A feedback signal of the closed loop control system is then generated according to the loop bandwidth. Finally, an input signal of the closed loop control system is compensated with the feedback signal to generate the output signal.
