| Abstract: | A novel speed sensor-less inverse decoupling control scheme of induction motors based on EKF is proposed in this paper. First, the inverse system method is used to realize the dynamic decoupling between rotor speed and flux. Then, an extend Kalman filter(EKF)is used to estimate the rotor speed and flux online. Last, the speed and flux regulators are designed respectively according to the linear system theory, so as to the speed sensor-less inverse decoupling control of induction motor is achieved. Simulation results show that the EKF can give the accurate estimates of rotor speed and flux in all drive range, and the proposed control scheme processes the perfect dynamic and static performance. |
