2) for the speed of the two control system timer switch is difficult to strictly maintain synchronization,
In the case of large changes in the speed of the measurement accuracy can not guarantee the speed.
So the application of the speed method of the traditional speed loop
design program is difficult to improve the servo drive speed to follow and control performance [1]
伺服驱动器是现代运动控制的重要组成部分，被广泛应用于工业机器人及数控加工中心等自动化设备中。
尤其是应用于控制交流永磁同步电机的伺服驱动器已经成为国内外研究热点。
当前交流伺服驱动器设计中普遍采用基于矢量控制的电流、速度、位置3闭环控制算法。
该算法中速度闭环设计合理与否，对于整个伺服控制系统，特别是速度控制性能的发挥起到关键作用[1]  。
In the servo drive speed closed loop, the motor rotor real-time speed
measurement accuracy is very important to improve the speed and
speed of the speed loop control dynamic and static characteristics.
To find the balance between measurement accuracy and system cost,
the general use of incremental photoelectric encoder as a speed sensor,
M/T测速法虽然具有一定的测量精度和较宽的测量范围，但这种方法有其固有的缺陷，
主要包括：1）测速周期内必须检测到至少一个完整的码盘脉冲，限制了低可测转速；
2）用于测速的2个控制系统定时器开关难以严格保持同步，
在速度变化较大的测量场合中无法保证测速精度。
因此应用该测速法的传统速度环设计方案难以提高伺服驱动器速度跟随与控制性能[1] 
Corresponding to the commonly used velocity measurement method for the M / T speed method.
M / T speed method although has a certain measurement accuracy and a wide range of
measurement, but this method has its inherent shortcomings,
Mainly include: 1) the speed cycle must be detected at least one
complete code pulse, limiting the minimum measurable speed;
