摘　　要：根据行波型旋转超声电机两相振动模态与输出转矩的关系,提出了两相振动模态的协调控制的TRUM优化运行方法。首先,根据定子的等效电路模型,提出两相模态观测器的构建方法;其次,提出以一相模态为参考,动态地对另一相进行控制的协调控制方法,以达到两相模态幅值相等、相位互差90°的电机优化运行状态,从而减小输出转矩脉动,使电机运行更加稳定。最后,通过仿真和实验验证了所提出的控制方法的有效性。An optimized operation method for travelling-wave type rotary ultrasonic motors was put forward by the coordinated control of two-phase vibration modes, in which the relationship of the vibration modes and the output torque was considered. Firstly, the observer of the two-phase vibration modes was built through the equivalent circuit model of the stator. Then, the coordinated regulation of dynamically controlling one phase mode by reference to the other phase was proposed to optimize the motor operation state, which expected the same mode amplitude and 90% phase difference of the two phases. By this method, the torque ripple will be reduced and the motor will run more steadily. Finally, the effectiveness of the method is verified by the simulations and experiments.
