为了满足现代工业对音圈电机定位平台系统高速和高精度的要求,实现音圈电机对力、位控制高速和高精度的目的,基于直线音圈电机的数学模型,采用力补偿控制原理,设计了力补偿控制器,通过对电流环等的设计,实现了音圈电机负载力与控制电压信号的转化,从而精确快速地控制电机。实验和仿真结果表明,采用力补偿控制可以实现系统对力和位置控制指令的快速响应和跟踪。
In order to meet the requirements of high speed and high precision of the voice coil motor positioning platform system in modern industry and achieve the purpose of high speed and high precision control of the voice coil motor, based on the mathematical model of the linear voice coil motor, the force compensation control principle is adopted and the design Force compensation controller, through the design of the current loop, etc., to achieve voice coil motor load and control voltage signal conversion, so as to accurately and quickly control the motor. The experimental and simulation results show that the force compensation and position control commands can be quickly responded to and tracked by force compensation control.
