Abstract

This paper presents a new efficient and systematic method to optimize the gain of the Linear Parameter-Varying (LPV) observer for a surface-mounted Permanent Magnet Synchronous Motor (PMSM). The said gain will be calculated by convex optimization to induce a convergence of the observer in a predetermined speed range. An extension of the observer to zero-speed estimation of position is also proposed, using a new model of the machine taking an injection signal into account, and without the use of saliency.
