Abstract

This thesis proposes the development of the indirect vector control for PMSM drive. The indirect vector control requires the relationship of the motor differential equations. Therefore, this thesis proposes a mathematical model of the PMSM to study the PMSM operation and design the indirect vector control. The aim of this thesis is to improve the speed response of the PMSM compared with the reference speed and reduce the vibration effect of the PMSM. For this reason, the controller improvement for the indirect vector control was studied and confirmed through the simulation of the indirect vector control for PMSM drive by software-in-the-loop embedded software technique on MATLAB/Simulink program. This technique is used to verify and compare the controller performance in each type. The simulation results show that the predictive speed controller operated with the model predictive current controller provides a fast and accurate PMSM speed tracking performance and can reduce the PMSM torque ripple. In addition, this thesis also presents the simulation of the indirect vector control by processor-in-the-loop embedded software technique to verify and evaluate the proposed controller before real hardware implementation.
