Summary: | Because of the
complicated energy conversion process,
ultrasonic motor has remarkable nonlinearity.
Therefore, it is difficult to achieve accurate
speed control of ultrasonic motor. In general, a
good model is the foundation of the accurate
control effect. Because of the remarkable
non-linearity of ultrasonic motor, the model
should also be nonlinear. In this paper, the
two-input and one-output steady-state model of
ultrasonic motor system is worked out using
fuzzy reasoning modeling method. Comparison
between experimental data and calculated data of
the model prove that the model can well
simulate the nonlinear relationship among the
amplitude of driving voltage, frequency, and
rotating speed. |
