Self-tuning Fuzzy Speed Controller of Travelling Wave Ultrasonic Motor
Aiming at the nonlinear characteristic of ultrasonic motor, some control strategies have been proposed to control the rotating speed of ultrasonic motor. But most of these strategies are too complex to realize using a low-cost embedded device. In this paper, a simple fuzzy speed controller is designed for ultrasonic motor. Until now, there has no mature and theoretic design method of fuzzy cont...
متن کاملImplementation of Adaptive Neuro Fuzzy Inference System in Speed Control of Induction Motor Drives
A new speed control approach based on the Adaptive Neuro-Fuzzy Inference System (ANFIS) to a closed-loop, variable speed induction motor (IM) drive is proposed in this paper. ANFIS provides a nonlinear modeling of motor drive system and the motor speed can accurately track the reference signal. ANFIS has the advantages of employing expert knowledge from the fuzzy inference system and the learni...

متن کاملA Traveling Wave Ultrasonic Motor Using Polymer-based Vibrator
Having natures of low speed, high torque and quick response characteristics, ultrasonic motors (USM) are applied in robot, precision machine and optical instruments. A lightweight actuator is essential to decrease the total weight and increase the operability. Although USMs, in general, are superior to conventional electromagnetic motor in torque/weight ratio, lighter motor is demanded. In this...
