| 摘 要： | 针对图像跟踪中对转台响应快、定位精度高的要求,设计了以ARM和轴角转换芯片组成的位置伺服控制系统。系统使用轴角转换芯片采集旋转变压器反馈的位置信息,通过IR2130驱动MOSFET功率管构成的H桥电机驱动电路,采用带有速度前馈加速度前馈的PID调节算法实现了直流电机位置伺服控制。试验结果表明该控制系统能够满足图像跟踪中对转台快速性和准确性的要求。

| Abstract: | Considering the requirements of short response time and high positioning accuracy for turntable in image tracking,a position servo control system based on ARM and RDC is presented.In this system,RDC is used to gather the position information from resolver,and the H bridge circuit based on MOSFET is driven by IR2130.At last,DC motor position servo control is successfully completed by PID control algorithm with speed and acceleration feedforward.The results of experiments show that this control system can satisfy the speed and accuracy requirement in image tracking. |
