Abstract :
Control strategies for an interior permanent magnet (PM) machine suitable for field weakening are considered. Different control approaches are investigated to identify a robust and fast torque control scheme. The use of a flux-oriented reference frame is suggested, mainly for control robustness reasons. A flux observer is proposed which minimizes the sensitivity to errors in the measurements and in the magnetic model. The torque control problem is analyzed in depth, from dynamic and steady-state points of view. An allowable operating area in the state plane is selected, and the related boundaries are implemented in the control scheme. Simulated behaviors are given, together with the experimental ones obtained from a prototype drive.<>
