Phase current control of a two phase synchronous reluctance machine

This paper presents a direct phase current controller for a two phase synchronous machine. Firstly, the machine is modelled in three domains : the electrical domain, the electromagnetic domain and the mechanical domain. Secondly, a linearised model is deduced for the RS controller coefficient determination. The performance is enhanced with the introduction of a model observer to compensate the system variations around its nominal point Afterwards, a full order RS controller with an augmented bandwidth is tested and is proved to be an alternative to the model observer. Finally, the three controller configurations are implemented on a test bench and the experimental results proved what was found in simulation.
