چکیده

This paper investigates the influence of the power converter on the performance of Surface Mounted Permanent Magnet Synchronous Motor Drives, which employ High Frequency Voltage Injection to achieve low speed control. The effects of IGBT voltage drop, deadtime and deadtime compensation on position estimation are discussed and the use of Matrix Converter is proposed to reduce these effects. Space Modulation Profiling technique is used to furher improve the estimated angle. Experimental results demonstrate the remarkable performance of the sensorless speed control employing the Matrix Converter and the contributions of the Space Modulation Profiling technique.

A sensorless speed-tacking controller for permanent magnet synchronous motors with uncertain parameters

This paper focuses on the so-called sensorless speed-tracking control for permanent magnet synchronous motors. A control strategy is proposed allowing to extract rotor position using electrical signals and an observer of electrical variables, and to guarantee the robust asymptotical tracking of a reference speed without measuring rotor velocity and position. Bounded parameter variations are sup...

Adaptive Voltage-based Control of Direct-drive Robots Driven by Permanent Magnet Synchronous Motors

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
