Design of an Actuator Controller Based on Frequency Feedforward Parameter Compensation

Abstract

The actuator controller is the key component of the active vibration control system. With the rapid development of microelectronics and power electronics in recent years, the control type actuator controller technology based on high-frequency pulse width modulation (PWM) pulse signal has become a research hotspot. At present, the actuator controller generally adopts the classic PID as the control strategy, but this classic PID control strategy is more suitable for controlling fixed loads and has poor real-time performance for dynamic load control.In response to this issue, this article improves the design of the control algorithm and proposes an actuator controller based on frequency feedforward parameter compensation PID control strategy. This strategy improves the real-time and dynamic load response capabilities of the control, with good current waveform following and low distortion. It can effectively improve and enhance the control effect, providing new ideas for the design of subsequent actuator controllers.
