关键字：Ultrasonic motor gyro-stabilized platform yaw and pitch control robust proportional-integral-derivative

摘要：This article specially designed and demonstrated a new ultrasonic motor and its control system based on the dynamic model of the 2-degree-of-freedom gyro-stabilized platform. The factors such as mechanical resonance, torque and moment inertia coupling, and nonlinearity of the driver were also taken into account during the optimization of the robust proportional-integral-differential control system. Finally, the controller was implemented by an ultrasonic motor and an embedded microcontroller. Experimental results showed that, comparing with the traditional electromagnetic motor controller, the proposed ultrasonic motor controller had the better control performances in dynamic response, static accuracy, isolation, and so on. A practical prototype of the gyro-stabilized platform with stronger robustness was also developed at the same time.
