SPEED CONTROL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES



ABSTRACT :

A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resista ....etc

Abstract
This paper introduces a sensorless nonlinear control
scheme for controlling the speed of a permanent magnet
synchronous motor (PMSM) driving an unknown load torque.
The states of the motor and disturbance torque are estimated via
an extended nonlinear observer avoiding the use of mechanical
sensors. The control strategy is an exact feedback linearization
law, with trajectory tracking evaluated on estimated values
of the PMSM states and the disturbance torque. The system
performance is evaluated by simulations.

Abstract
This paper present a speed control technique for effectively meeting the motion control objective which is
a permanent magnet synchronous motor (PMSM) based on an embedded inside current tracking objectives. The tracking
adaptive backstepping technique. The proposed stabilizing controllers described in this paper fall into the category of a
feedback law for the PMSM is shown to be globally full state-feedback controller with system uncertainty. In this
asymptotically stable in the context of Lyapunov theory. It takes sch ....etc

ABSTRACT
Permanent magnet synchronous motor (PMSM) has been widely used in high performance drive applications for its advantages such as compactness, high efficiency, reliability and suitability to environment. Due to its high power density and smaller size, PMSM has evolved as the preferred solution for speed and position control drives on machine tools and robots. A Permanent Magnet Synchronous Motor (PMSM) is a motor that uses permanent magnets to produce the air g ....etc

Abstract
A new concept in Urban Maglev transportation design is in the testing phase. The vehicle uses
permanent magnets (PM) for both the electro-dynamic suspension (EDS) and linear synchronous
motor (LSM) propulsion. Because of the 3D coupled non-linear velocity-dependent magnetic
levitation, the LSM must provide stabilizing forces to the vehicle. To do this, Vector Control is used
