Design of m-IPD controller of multi-inertia system using Differential Evolution

In this paper, a new design method of vibration suppression controller for multi-mass (especially, 2-mass) resonance systems is proposed. The controller consists of a digital modified-IPD controller for speed loop and a digital PI controller for current minor loop. The six controller gains are determined by Differential Evolution algorithm. The Differential Evolution is one of optimization techniques and a kind of evolutionary computation technique. In this paper, we have applied the DE/rand/1/bin strategy to design swift the optimal controller parameters. Furthermore, we consider the parameter identification method of 2-inertia experiment system by the Differential Evolution. Finally, the effectiveness of the proposal methods has been confirmed by the computer simulations and the experiments.
