Abstract
A general-purpose control algorithm is proposed for permanent magnet (PM) synchronous machine drives based on the principles of Direct Flux Vector Control. The algorithm does not require regulators tuning, and it is tailored to different machines automatically via identification of the stator resistance and flux linkage tables. The model parameters are identified via a preliminary self-commissioning procedure that can be integrated into the standard drive firmware with no need for extra hardware or off-line manipulation. The combination of the control and self-commissioning algorithms forms a “plug-in” controller, meaning a controller that is capable of exploiting the full drive capabilities with no prior knowledge of the PM machine in use. Experimental results are reported for two prototype concentrated-winding PM machines designed for traction applications, one with a surface-mounted PM rotor and the other with an Interior PM magnet rotor.
