基于增量式光电编码器的高精数字测速应用研究

针对改进M/T测速法中的不足,分析原因主要是没有考虑处理器执行代码需消耗时间,增加计算误差,于是提出在改进M/T测速法中对高频时钟脉冲分频方法,有利于提高测速精度和改善速度调节器的稳定性。改进的方法在带负载的真实实物系统中提高了测速精度,为整个交流电机调速系统的实现提供了保障。

The applied study of high accuracy digital velocity measurement on photoelectric encoder

This paper introduces the problem in the modified M/T method of digital velocity measurement,analyzes the mainly reason is that processor consume time is not calculated,to increase calculated error.The goal of this research is search a method to decrease error and improve its stability.The approach used the high frequency clock pulse frequency division method.It is a result that improved accuracy and improved speed regulator stability.use of software debugging in the real physical system with a load to achieve a high precision digital speed,and provide a guarantee for AC motor speed control system.
