Discrete Current Control Strategy of Permanent Magnet Synchronous Motors

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...

Voltage Control Strategy for Direct-drive Robots Driven by Permanent Magnet Synchronous Motors

Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...

Optimization of Current Excitation for Permanent Magnet Linear Synchronous Motors

The main problem in improving the tracking performance of permanent magnet linear synchronous motors is the presence of force ripple caused by mismatched current excitation. This paper presents a method to optimize the current excitation of the motors in order to generate smooth force. The optimized phase current waveforms produce minimal ohmic losses and maximize motor efficiency. The current ...
