This paper presents the methods used in speed control of Permanent magnet synchronous motor (PMSM) drives. Permanent magnet synchronous motor(PMSM) are widely used in AC servo drives because of its high torque to inertia ratio, high power density, high efficiency and power factor as compare to the other motors used in drives. The study shows that the methods used to improve the performance of P...

The main theme of this paper is to present novel controller, which is a genetic based fuzzy Logic controller, for interior permanent magnet synchronous motor drives with direct torque control. A radial basis function network has been used for online tuning of the genetic based fuzzy logic controller. Initially different operating conditions are obtained based on motor dynamics incorporating...

This paper presents a simplified fuzzy logic-based speed control scheme of an interior permanent magnet synchronous motor (IPMSM) above the base speed using a flux-weakening method. In this work, nonlinear expressions of d-axis and q-axis currents of the IPMSM have been derived and subsequently incorporated in the control algorithm for the practical purpose in order to implement fuzzy-based flu...

In an electrolytic capacitor-less inverter, source current harmonics are caused by LC-circuit resonance, and the power factor deteriorates. Therefore, inverter must reduce control without additional circuits. This paper proposes a method to in three-phase of permanent magnet synchronous motor drive. The proposed consists using full-state feedbacks LC-resonance state observer. validity is confir...

The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.

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...

High Torque Low Current (HTLC) Starter is the new innovative motor soft starter system. This is a motor starting method for high inertia loads using a low voltage drive with input and output transformers to control motor torque and limit current when starting a medium/high voltage motor. The HTLC is a solution to motor starting problems where Direct on Line (DOL) or “Across the Line” starting i...
