中文摘要：

提出了一种新的自适应M/T电机测速算法.该算法通过预置电机转速大致输出时间间隔来实现测量的实时性,通过光电编码器脉冲计数的动态自适应调整来保证测量精度.仿真实验证明,该算法在保证测量精度的同时,相对于传统M/T算法,在测量低转速的情况下其实时性有了显著提高.

英文摘要：

A new adaptive M/ T method was introduced to measure motor speed. The method preseted an approximatetime interval of output motor speed to improve the teal-time. And the counter of photoelectric encoder pulse can be adjustedadaptively to assure required precision. Simulation results show that the adaptive M/ T method has both high precision andbetter real time performance especially when motor was in low speed compared with traditional used M/ T algorithm.
