Current Reference Governor of Permanent Magnet Synchronous Machine

This paper presents a control method for constrained control of a permanent magnet synchronous machine. The control system utilizes field oriented PI current control tuned using linear control theory to obtain good steady- state performance and a fast transient response. However, the linear control theory does not consider constraints, violation of which may lead to performance deterioration and even instability. In order to ensure constraint satisfaction an additional device called a reference governor is added to the existing control loop. The main advantage of such add-on device is in its simplicity and its low computational burden which enables real time implementation. The real time feasibility of the proposed method is shown using a processor-in- the loop simulation implemented on Texas Instruments F28335 150 MHz micro-controller.
