Abstract
This project deals with the control of an IPMSM. The objective of the project is to implement and investigate a control structure that is able to drive the motor in Field Weakening(FW) mode. In order to reach this objective, first a Field Oriented Control structure is implemented in Matlab/Simulink with a Maximum Torque per Ampere control. Then a FW control algorithm that acts on the angle of the stator current vector is investigated and implemented in the overall simulation model. The presented simulation results prove that the implemented method is capable of FW, with good speed and torque dynamics. The designed control is then implemented in a dSpace control system. The experimental results that are presented at the end confirm the fact that the FOC is working, and is capable of FW regime.
