In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop MITSUBISHI MR-J3-11KB-RJ080W PDF catalog.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the mminimum detectable speed MR-J3-11KB-RJ080W datasheet.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is largger MR-J3-11KB-RJ080W PDF datasheet .
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
