Abstract

This project focuses on the development of a PMSM drive system based on model predictive control (MPC). This thesis explains the overall performance analysis of torque, speed, and current control. Moreover, the goal of this method is to improve the step response, and to reduce THD and torque ripple of the system. The performance of the MPC is compared with FOC using MATLAB/Simulink. PMSM drive provides many advantages such as high torque, high efficiency, and low noise. The developments of PMSM drive make it desirable for motion control applications. However, due to PMSM's extremely nonlinear characteristics, it needs a more complex controller (advanced controller) to achieve high-performance drive applications. Therefore, in the last decades, PMSM has been applied to several variable speed drive methods. Among these, controller vector control is the most popular. Moreover, vector control is represented by the main types, field-oriented control (FOC) and direct torque control (DTC) with the PMSM drive considered as high dynamic drives. However, the dynamic response can be improved by using MPC with less complexity and higher efficiency. Finally, the simulation results have verified the effectiveness of the MPC method for PMSM drive compared the FOC controller
