Abstract(in English) | Ultrasonic motor (USM) is a special type motor, which is driven by the ultrasonic vibration force of piezoelectric elements. It has an excellent performance and many other useful features, e.g., high torque, low speed operation, compact in size, no electromagnetic interferences, and so on. However, this motor has a nonlinear speed characteristics, which vary with drive conditions associated with a temperature and applied load torque of USM. Accurate speed information is necessary to realize high performance and high-precision speed control of an ultrasonic motor. The rotor speed is measured by using mechanical sensors such as resolvers or pulse encoders. However, these sensors are usually expensive and bulky. Therefore, the cost and size of the drive system are increased. The use of neural network to identify nonlinear characteristics is very useful because of nonlinear identification ability. The validity of the proposed method is confirmed by experimental results. |
