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]
伺服驅動器是現代運動控制的重要組成部分，被廣泛應用于工業機器人及數控加工中心等自動化設備中。
尤其是應用于控制交流永磁同步電機的伺服驅動器已經成為國內外研究熱點。
當前交流伺服驅動器設計中普遍采用基于矢量控制的電流、速度、位置3閉環控制算法。
該算法中速度閉環設計合理與否，對于整個伺服控制系統，特別是速度控制性能的發揮起到關鍵作用[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測速法雖然具有一定的測量精度和較寬的測量范圍，但這種方法有其固有的缺陷，
主要包括：1）測速周期內必須檢測到至少一個完整的碼盤脈沖，限制了低可測轉速；
2）用于測速的2個控制系統定時器開關難以嚴格保持同步，
在速度變化較大的測量場合中無法保證測速精度。
因此應用該測速法的傳統速度環設計方案難以提高伺服驅動器速度跟隨與控制性能[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;
