摘要
根据开放式运动控制的要求,以DSP和CPLD为核心设计了能实现高速、高精度插补功能的开放式伺服电机运动控制器。介绍了控制器硬件构成、工作原理。控制器通过PCI或USB总线与上位机通讯,位置环采用速度、加速度前馈PID控制算法。实验和仿真结果表明控制器控制实时性好,跟随误差小,加工精度高。
This paper presents an open controller based on DSP and CPLD. The controller can perform high speed and high accuracy interpolation. The hardware and the principle of the motion controller are introduced. The controller communicate with the upper computer through PCI or USB bus The control algorithm of the position loop is the PID law with speed and acceleration feedforward. Experiments and simulation results are given.
