摘要

为了提高光电编码器动态检测技术的稳速精度，设计了基于永磁无刷直流电机的转台驱动系统。分析了动态检测转台工作时速度波动对编码器角度误差的影响；结合空间矢量法建立无刷电机三相绕组的力矩合成模型，使合成力矩在空间内任意位置幅值相同；最后加入PI控制器，并利用DSP+CPLD设计了驱动电路，以保证电机匀速转动，并可模拟编码器在实际应用中的各种转动方式。实验结果表明：设计的编码器动态检测转台驱动系统在高、低速转动时都能保持恒定的转矩输出，系统稳速精度高，稳态误差小于±1（°）/s。另外，转台驱动系统转动稳定，有效降低了速度波动对编码器误差检测的影响，满足光电编码器动态检测的要求。

Abstract

To increase the measurement precision of dynamic detection for an optical encoder in the steady speed

a turntable drive system with a brushless DC motor was designed. The influence of the speed fluctuation of dynamic detection equipement on the angle errors of the encoder was analyzed. A model of winding torque composition with space-vector was set up to make the torque's value to be a constant. Finally

the PI controller was added to this system

and the drive circuit was designed with a DSP+CPLD. The experiment shows that the drive system of dynamic detection equipment for the encoder can mantian the output torque stable in all the speeds. The steady speed precision of the system is better

and the steady error is less than ±1 (°)/s. The stable drive system effectively reduces the effect of speed fluctuation on the detection error and satisfies the dynamic detection requirement of photoelectric encoders.
