摘　　要：在伺服驱动器的设计中,电机速度的测量或计算是一个非常重要的环节。虽然常规的M/T法可以实现电机高低速的有效测量,但当速度变化较大时,这种方法不仅使得速度测量的连续性变差,而且还会带来较大的测量延时。为了改善上述问题,设计了一种新型的基于FPGA的速度滑动测量和估算策略,通过仿真证明此方法的有效性。In the design of servo driver, the algorithm of velocity for motor is very important. Custom M/ T method was adopted to achieve effective measure both in high and low velocity rang of motor. However, when the velocity of motor fluctuated shapely, the continuity of velocity measure would be worse, and the measure delay would be large. For improving these problems, a novel gliding algorithm of velocity was de signed based on FPGA for a new servo structure with two loops in high sample frequency. At last, the results of simulation have proved the effectiveness of the approach.
