Robust Control Strategy to Parameter Variations for an Interior

Abstract:- The interior permanent magnet (IPM) synchronous machines have several desirable features for automotive, tools machines and residential drive applications. When operating over a wide speed range, the main problem is to assure a proper and automatically set flux weakening. The paper presents a control structure of an IPM synchronous machine proper to be used also in the motoring regime, generating regime or in an integrated starter-generator regime. The control algorithm assures insensitivity to the load parameters variation. Experimental results for both cranking and generation are shown and analyzed. Key-Words:- synchronous machine, interior permanent magnet, flux weakening, vector control
