Abstract :
This paper proposes an adaptive backstepping based nonlinear controller for high speed control of an interior permanent-magnet synchronous motor (IPMSM) particularly, above the rated speed. This controller incorporates both torque and flux controls with parameter estimation adaptively. The nonlinear backstepping controller is introduced in order to introduce high performance speed tracking. The controller with constant parameters will lead to an unsatisfactory prediction of the performance because of nonlinear operation of interior permanent magnet synchronous motor owing to the magnetic saturation of these machines particularly at high speed conditions. In this work, an adaptive backstepping based control technique, considering system parameter variation, has been developed for an IPMSM. The proposed adaptive backstepping based high speed control of IPMSM drive is successfully implemented in real time for a laboratory 1 hp IPMSM drive. The efficacy of the proposed drive is verified both in simulation and experiment at different operating conditions. Form the results it can be concluded that the proposed controller is robust to dynamic uncertainties and can reject any bounded immeasurable disturbances entering the system. The voltage level control inputs are designated to follow the command speed using backstepping technology.
