Nearly all of the electrical power used throughout the world is generated by synchronous machines driven by either hydro or steam turbines or by combustion engines. Synchronous Machine is generally dedicated to high power due to the fact that they have a controllable power factor and a higher efficiency than the induction motor of corresponding rating. In recent years different control schemes ...

The paper describes a study and an experimental verification of remedial strategies against failures occurring in the inverter power devices of a permanent-magnet synchronous motor drive. The basic idea of this design consists in incorporating a fourth inverter pole, with the same topology and capabilities of the other conventional three poles. This minimal redundant hardware, appropriately con...

This paper aims to develop vector controlled permanent magnet linear synchronous motor (PMLSM) based on simplified space vector pulse width modulation. Mathematical models of PMLSM&SVPWM presented. The present PWM technique does not involve any sector identification and considerably reduces the computation time when compared to conventional space vector PWM technique. To validate the proposed a...

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...

In this paper, the speed tracking for permanent magnet synchronous motor (PMSM) in field oriented control (FOC) method is investigated using linear proportional-integral (PI) controller, sliding mode controller (SMC) and its advanced counterparts. The advanced SMCs considered in this paper are fuzzy SMC (FSMC) and sliding mode controller with time-varying switching gain (SMC+TG) which can effec...
