Abstract
This paper proposes a non-iterative approach for the identification and suppression of high-frequency vibration induced by mechanical resonance, aiming to improve motor control accuracy. First, a structured pole-zero model is developed to characterize the system's resonance and anti-resonance dynamics. Unlike conventional methods that rely on iterative parameter search, the proposed approach directly extracts system parameters from the measured frequency response, eliminating the need for manual adjustment or iterative optimization. The identified model is then inverted to design a resonance filter that effectively attenuates vibration. The method is experimentally validated on a galvanometer scanner, a representative high-speed servo motor system used in precision laser processing. Compared to a conventional empirical model, the proposed non-iterative approach achieves comparable modeling accuracy while significantly reducing identification time, demonstrating its effectiveness for vibration mitigation in precision motor control.
