Abstract

This paper presents a novel deadbeat feedforward compensation in the fast and precise positioning control for mechatronic systems. The proposed compensator is designed considering the frequency shaping in control input to suppress the residual vibration, under the constraint of specified step number in position reference. A 2-degree-of-freedom positioning controller with the deadbeat feedforward compensation can ensure the required settling performance with the specified steps regardless of the positioning amplitude in reference. The effectiveness of the proposed approach has been verified by numerical simulations and experiments using a prototype of Galvano scanner.
