The　applied　control　strategy　must　be　robust　to　permanent　magnet　synchronous　generator　(PMSG)　parameter　variations　and　unknown　disturbances　to　achieve　the　stability　of　generating　operation　of　permanent　magnet　synchronous　generating　system.　The　techniques　of　nonlinear　feedback　linearization　and　internal　model　control　were　combined　to　propose　a　novel　PMSG　control　strategy.　In　the　proposed　control　strategy,　a　PMSG　mathematical　model　in　stator　coordinate　frame　was　used　as　the　internal　model,　and　then　the　output　error　dynamic　system　between　actual　PMSG　and　internal　model　was　expanded　into　a　new　nonlinear　error　system　by　one-order　low　pass　filters.　At　last,　the　stator　voltage　vector　reference　was　calculated　with　the　help　of　the　input-output　linearization　theory　according　to　the　new　error　system.　The　experimental　results　show　that　the　generating　system　with　the　proposed　control　strategy　has　an　ideal　tracking　performance　of　torque　and　stator　flux　linkage　amplitude,　and　a　high　robust　ability　to　parameter　changes　of　PMSG　and　load　disturbance,　and　quick　and　smooth　control　performance　for　DC　voltage　with　low　operation　noise.　©　2013　Chinese　Society　for　Electrical　Engineering.
