Analysis And Design

This paper focus on various loading conditions onthe Permanent Magnet Synchronous Motor and its application using field oriented control technique. Constant torqueapplication irrespective of speed isalso presented. This technique helps in lift and belt conveyors handling constant weight of material per unit time, in pumping and compressing and electric locos. Results of simulation shows that proposed system has high acceleration and deceleration rate with vector control,overall quick and dynamic response as well as excellent controlling ability. The vector control is a excellent technology for analysis and design of PMSM drive system. It provides designing and debugging for practical drive system. Modeling and different kinds of Permanent Magnet Synchronous Machines are studied and Simulation is carried out in Matlab and performance is studied at different operating conditions.

This paper focuses on modeling and closed-loop speed control of a three-phase Permanent Magnet Synchronous Motor (PMSM) fed by a Matrix Converter (MC) based on Field-Oriented Control (FOC). The model considers a set of a small input filter with supply impedance or cable effect, to improve the quality of the input current. A simplified form of the Venturini modulation algorithm is used for switching the matrix converter and a comparative study of two types of speed controllers is presented, namely a proportional integral (PI) and a proportional integral (PI) to improve performances of the drive system in transient and stable conditions. The overall drive system is simulated using Matlab/Simulink environment. The motor performance is evaluated under different operating conditions such as sudden changes in the load or changes in the angular speed reference. The results of the converter MC gives unlimited output frequency, sinusoidal input current and output voltage waveforms and unity input displacement factor. The IP controller is shown to achieve better performance of the speed control loop, with or without the load torque as compared to the PI classic controller.
