Industrial automation have been developed mostly the around of motion control systems in which the controlled electric motor have vital role as heart of system. So, motor control systems with a very good performance to a large extent result in optimum performance of the automation of production that this work is associated with increased production and quality of products. In fact, the performance of modern automation systems, which in terms of speed, accuracy, flexibility and performance are defined, mainly related to control strategies. Recent developments in the power electronics industry has led to a significant increase of power that can exchanged by semiconductor equipment. Despite this, most voltage supported by this equipment is a major obstacle in the applications of medium & high Voltage. Multilevel converters have been introduced for such applications. These inverters have less harmonic distortion compared with standard two-level inverters when they are working a switching frequency. Permanent magnet synchronous motors (PMSM) newly developed with high energy permanent magnet materials if properly controlled can provide fast dynamic and performance with high efficiency and compatibility are very good in various applications. In spite of all these, motor control including PMSM control is a challenge due to dynamic of very fast motor and very linear models of machines. So, much of motor control development includes extraction of appropriate mathematical models. Modelling & simulation is performed on MATLAB\SIMULINK software.
