Fuzzy controller of multi-inertia resonance system designed by Differential Evolution

In this paper, a new design method of vibration suppression controller for multi-mass (especially, 3-mass) resonance systems is proposed. The controller consists of a fuzzy controller for speed loop and a PI controller for current minor loop. The three scaling factor of the fuzzy controller and two PI controller gains are determined by Differential Evolution (DE). Comparing with the conventional design algorithm, the proposed technique is able to shorten the time of the controller design to a large extent and to obtain accurate results. Finally, we confirmed the effectiveness of the proposal method by the computer simulations.
