摘要
通过对直线电机进给伺服系统的结构特点和组成原理进行分析 ,推导出直线电机进给系统控制模型 ,利用Matlab&Simulink软件对模型进行了仿真 ,并结合GD - 3型直线进给单元的伺服刚度的实验研究 ,分析了控制参数对直线电机伺服刚度的影响规律。
The characteristics of structure and controller of the linear feed drive were discussed, the model of the linear feed system with disturbance forces was developed and the transfer function was built up. According to the proposed model,dynamic stiffness of the linear feed drive was investigated with simulation software Matlab & Simulink, while the influences of the control parameters on the feed drive dynamic servo stiffness were evaluated. The simulation results were also verified by the dynamic stiffness experiments on a high speed feed unit,type GD-3.
