Resonant Frequency Tracking Control of Novel Moving-Magnet Type Linear Oscillatory Actuator
摘要
Abstract
Aiming at a novel moving-magnet type linear oscillatory actuator, the mathematical model of the actuator electromechanical system was established and the resonant characteristic was analyzed. The results show when the operating frequency is equal to the mechanical resonant frequency, the actuator has the highest efficiency, and the phase angle difference between the current and displacement is 90o. Combined with the mover displacement estimation method, the resonant frequency tracking control system was proposed, which is based on the phase angle difference method. The simulation results show that this resonant frequency tracking strategy can adjust the operating frequency of the actuator to the varied resonant frequency, which makes the actuator operate with high efficiency.关键词
