Digital speed control of multi-inertia resonant system using real time simulator

In this paper, a robust vibration suppression control method for a multi-inertia (a three-inertia and a four-inertia) system by a digital modified-IPD controller is proposed. The controller consists of integral, proportional, derivative and time lag of first order element. We apply the Taguchi Method for the determination of the controller gains for several noise factors (load side inertias and stiffness of the shafts). To confirm the effectiveness of the controller structure with several conditions and the tuning method, we use a real-time simulator based on a RTLinux.
