中文摘要：
针对传统实验平台中的数控转台采用伺服电机作为运动部件、通过蜗轮。蜗杆传动而产生的运动速度低、动态响应差等不足，设计了一种基于可编程多轴控制卡PMAC的开放式运动控制转台实验系统。该系统以PMAC为控制核心，直驱电机作为运动部件，以高精度的光栅传感器作为反馈元件，采用谐波修正法建立传感器的误差分析模型，并采用Visual C＋＋设计开发了整套自动控制软件。实验结果表明：实验系统速度快、可靠性高，相比传统数控转台，运动速度瓶颈得到解决，动态响应明显改善。
英文摘要：
Aiming at the deficiency problem of low velocity, bad dynamic responses caused by using servomotor as motion mechanism to drive through worm and worm wheel for the numerical control （NC） Rotary Table in traditional experiment platform, a rotary table experiment system with open way motion control was designed based on the multi-axis programmable motion control card PMAC. By taking the PMAC as the control core in the system, the direct driver motor as motion mechanism, with the high precision Time Grating displacement sensor as feedback element, the error analysis model of sensor was established by adopting harmonic wave correc- tion method, and a complete set of automation software was developed and designed by using the Visual C ＋＋. The experiment results show that the experiment system has fast velocity and high reliability. As compared to traditional NC rotary table, its velocity bottleneck in motion is not only resolved, but also the dynamic responses are improved.
