| Popis: | A backstepping controller based on online multiparameter estimation is designed for permanent magnet synchronous motors (PMSMs). The online multiparameter estimator consists of an extended sliding-mode observer and affine projection algorithm. The extended sliding-mode observer is used to track mechanical system parameters in real-time of PMSM, and the affine algorithm is applied to identify the stator resistance, inductance, rotor flux linkage. The designed backstepping controller, which utilizes the accurate system parameters identified by multiparameter estimator in real time, achieves an exponential ultimate boundedness of control state variables with arbitrarily fast decay rate and arbitrarily small bound. The proposed controller is constructed only by static feedback of measured voltages and currents which makes the control input smooth and easy to implement without the needs of differentiation or switching operations. The simulation experiments are conducted by SimPowerSystems in MATLAB and the results show the validity of the proposed controller with online parameter estimator. |
