Optimal Design of Ultra-High Speed Axial Flux Permanent Magnet Motor with Sinusoidal Back-EMF

Passivity-Based Speed Control for Permanent Magnet Motors

This paper addresses the design, simulation and experimental validation of a Permanent-Magnet Synchronous Motor speed control. The control is based on the passivity strategy; special attention is paid on the stability control issue. SIMNON simulations illustrating the torque and speed response of the motor control are carried out to validate the control strategy. The algorithm control was progr...

A New Hunting Control Method for Permanent Magnet Hysteresis Motors

Hunting is a flutter associated with the synchronous speed that gives rise to the gyro drifting errors and may cause objectionable time-displacement errors in video head wheel drives and other precision scanning systems. In this paper, dynamic characteristics of permanent Magnet hysteresis motors are presented and hunting is explained. New damping techniques have been developed using optimi...

Scalar Control Systems with Permanent Magnet Synchronous Motors with Sinusoidal Current Control. Calculation of Speed Controller Parameters

The present paper presents the calculation of the speed controller parameters of the scalar control systems with permanent magnet synchronous motors with sinusoidal current control used in low power applications. The shaft position sensor used to determine the rotor position, respectively its rotation speed is made of two Hall sensors. In the considered numeric example, we presented the Bode di...
