It is very important to use two motors synchronization control in photoelectric theodolite tracking control system. First, the direct drive function of two motors is modeled. Compared with single motor direct control system, the resonance frequency of two motors control systems is the same, while the anti-resonance frequency of two motor control system is 1.414 times than those of sing motor system. Because of hard coupling for direct drive, the speed of two motor of the system is the same, and the synchronization of torque for motors is critical. The current master-slave control technique is effective to synchronize the torque, in which the current loop of the master motors is tracked by the other slave motor. The speed feedback into the input of current loop of the master motors. The experiments test the performance of the two motors drive system. The random tracking error is 0.011 9″for the line trajectory of 0.01°/s.
