Abstract
This study presents servo system design that simultaneously achieves vibration suppression and desired reciprocal motion of a wiper system. First, linear dynamics of a wiper system is derived based on theMaxwell’s frictional model. Next, a modal analysis is conducted to select modes to be controlled and derive reduced-order dynamics, which enables to provide smaller controller gains for improving safety and satisfying the voltage limitation of automotive batteries. A new servo system is presented, in which not only output reference but also desired signals of all states are assigned to significantly improve the tracking performance of reciprocal motion.
