초록
2DOF is applied to induction moor in order to supply these weak points of PI speed control method in this paper. and proposed method utilize the combination of the voltage model based on stator equivalent model and the current model based on rotor equivalent model, which enables stable estimation of rotor flux. And it also emphasizes the improvement of the control characteristics in low speed region where established schemes have many problems. To prove the propriety of this paper, the various simulations carried out adequacy and stability using Matlab, and at the same time real system is made, so it is proved. As the results of embodying the system, the robust system is realized.
