Abstract
In order to avoid the noise during the closure of contactors and to improve their electrical performances, we regulate the speed of the contactor mobile part movement. The prestressing force of the pole spring generates a perturbation on the speed when the moving contact touches the fixed contacts. By simulations, we see that a simple speed control is not sufficient. In this paper, we propose a feed-forward control included in the control strategy to compensate the prestressing force.
