大型工作台C轴双伺服直驱同步控制技术的应用

Application of synchronous control of large table C shaft with double- servo direct drive

实际消隙控制是在系统转矩输出为零的区域附近对两台电机施加一个足以克服间隙的转矩偏置,使得这一转矩范围内两台电机实施消隙驱动,而越过这个区域后,两台电机则协同出力。

Actual anti- backlash is to put a torque offset whick can remove the gap on two- molors near the place where the system output torque is zero,it makes the two motors in the torque range to perform backlash removing drive,and across the region,the two motors move collaboratively.
