Abstract

Abstract: A novel strategy applied closed-loop adaptive back-stepping control to permanent magnet synchronous generator (PMSG) is proposed targeting the problem of the modification of torque for mechanical elastic energy storage (MEES) system utilizing PSMG as power source. This paper establishes the mathematical model of MEES system and PMSG, and presents the closed-loop adaptive backstepping control which makes the angle between the dq axis oriented by the current of stator and the dq axis oriented by the rotor a constant value via the speed and current closed-loop based on the analysis of open-loop I/f control. The closed-loop adaptive back-stepping control can suppress the speed fluctuation, sensorless, overcurrent and improve the PMSG robustness by identifying the stator resistance and inductance of generator. The ideal control result can be proved in the state of startup and steady operation of PMSG.
