Abstract

Abstract: In allusion to the simultaneous time-varying characteristics of power source torque and moment of inertia in permanent magnet synchronous motor based mechanical elastic energy storage system, a parameter identification and L₂ gain based backstepping control strategy was proposed. Firstly, Time-varyring moment of inertia and input torque were simultaneously identified through the least squares algorithm with forgetting factor. Then, on the basis of identification results and combining backstepping control and L₂ gain disturbance suppression method, a nonlinear backstepping controller was designed against identification errors and parameters perturbation to ensure the rotating speed and output currents of PMSG to track the given references. The simulation results show that the outputs of PMSG can track the target values rapidly and the proposed strategy has a certain anti-interference ability.
