An active piezoelectric absorber for vibration control of electrical machine

This paper describes an analytical modeling established in the purpose of designing a vibration compensation method by piezoelectric actuators in Switched Reluctance Machines (SRM) and Flux Switching Machine (FSM). This analytical approach is the base of a simulation scheme which computes the efficiency of the compensation method considering geometrical parameters and topology variations. The closed loop control is realized with a robust controller feedback using the measure of the vibratory acceleration. This approach is compared to finite element (FE) simulations. The aim of this paper is to determine typical application background for this method illustrated with two examples: a SRM-starter-generator and a Flux Switching machine.
