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.

INTRODUCTION Permanent-magnet synchronous motors (PMSMs) are widely used in low and mid power applications such as in variable-speed drives, wind generation systems, electric vehicles and robotics, etc. PMSMs do not carry rotor currents. Moreover, eliminating copper in the rotor allows the design of machines with smaller rotor diameters, resulting in smaller machine size with higher power density and lower rotor inertia [1-2]. Thesefeatures contribute to the improvement of the efficiency of PMSMs as compared to induction motors (IM). Field oriented control (FOC) or vector control theory has become now a widely accepted solution for the control of AC motors drives [3-5]. Matrix converter-fed PMSM drives combine the advantages and attractive features of both the motor and converters technologies, and are emerging as a competing candidate drive technology for applications that require power-dense and volumetrically efficient electromechanical energy conversion with minimal distortion of supply-side power quality. One of the most attractive feature of matrix converters (MC) when compared to conventional voltage source inverter and active-rectifier combinations is the absence of a large DC link capacitance, since for high power applications this is a relatively expensive and bulky component which is widely recognized as having a significantly
