Passivity-Based Speed Control for Permanent Magnet Motors

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...

LMI-based Sliding Mode Speed Tracking Control Design for Surface-mounted Permanent Magnet Synchronous Motors

Abstract – For precisely regulating the speed of a permanent magnet synchronous motor system with unknown load torque disturbance and disturbance inputs, an LMI-based sliding mode control scheme is proposed in this paper. After a brief review of the PMSM mathematical model, the sliding mode control law is designed in terms of linear matrix inequalities (LMIs). By adding an extended observer whi...

Fractional Slot Permanent Magnet Synchronous Motors for Low Speed Applications

Digital Control of Permanent Magnet Synchronous Motors

Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...
