Design of vibration suppression controller for high order resonance system by Mutation-Type Grouping PSO

In this paper, a new design method of vibration suppression controller for multi-mass (especially, 6-mass) resonance systems is proposed. The proposed method is possible to suppress the mechanical vibrations of all modes. The controller consists of a modified-PI-PD controller for speed loop and a PI controller for current minor loop. The seven controller gains are determined by Coefficient Diagram Method (CDM). And then, we propose Mutation-Type Grouping Particle Swarm Optimization (PSO) to design a Coefficient Diagram of the CDM. 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.
