| Abstract: | In accordance with dynamic characteristics of induction motor system,the asymptotic tracking properties of the flux linkage and the rotor speed and the global stability of the system have been studied without the priori knowledge of the induction motor's parameters.The backstepping technique is applied in the design of the nonlinear controller and the estimation of the unknown induction motor' parameters.The output tracking of the induction motor for the given signals is realized by the proposed nonlinear adaptive controller.The global stability of the system as well as asymptotically track of the rotor flux linkage and the rotor speed of the system for reference signals is guaranteed.The simulation validates the efficiency of the control scheme. |
