Speed Sensorless Control of Linear Ultrasonic Motors Based on Stator Vibration Amplitude Compensation

In some applications of linear ultrasonic motors (LUSMs), not installing speed/position sensors can reduce the size and cost of the system, changes in load will cause fluctuations in the speed of the LUSM. To eliminate the influence of load changes on speed, a speed sensorless control scheme based o...
