Abstract In an induction machine vector control system, current sliding mode observer (CSMO) has a good suppression on rotor time constant variation, but stator resistance error will decay the performance. A stator resistance correction method, in which the flux error between the values of estimation and instruction is used to obtain the correction coefficient of stator resistance, is proposed to eliminate the effects caused by stator resistance variation. All the basic principle, theoretical derivation and control block diagram are introduced. Some simulations and experiments are done in a vector control system with current sliding mode observer. The results show that the proposed method can suppress stator resistance variation effectively, so the robustness of the system is increased.
