Sensorless control of AC drives has been a field of research for many years. Nevertheless, sensorless control at zero speed is still a challenge, especially for surface mounted Permanent Magnet Synchronous Machines (sPMSM), where the magnet saliency is really small.
The main goal of this project is to develop a sensorless control for a sPMSM able to work in zero and low speed.
Literature about sensorless control strategies is studied and the suitability of the proposed estimator is tested by simulations and experimental tests in various operating conditions. The proposed estimator method is stable in low speed, including loading conditions.
High frequency signal injection method strategy was implemented using Danfoss power converter and dSpace as well as Matlab/Simulink.
Even the topic of the project is sensorless control the simulations and the laboratory was also carried in close loop, in order to compare the results.
