Analysis the data of chaotic operation on ultrasonic motor system
Abstract
In this paper, we designed a closed loop control system of ultrasonic motor, found the phenomenon about the random irregular movement of motor-speed and analyzed the data of speed, simulated the bifurcation diagram of the speed about motor control system, calculated the speed of sampling value on the maximum Lyapunov index, the calculation result was greater than zero, it was further proved that the system was chaotic system.
