A forward-feed current decoupling vector control system, based on flux observation, was brought forward. The mathematical model of the induction motor system was presented. The simulation system, developed under Matlab/Simlink platform according to the real system, worked efficiently. The dynamical performance of forward feed current decoupling vector control system based on flus observation, was studied with this simulation system. The change of the system dynamical torque was accelerated to improve, the system dynamical performance. The system can be used to verify the controlling characteristics of vector control system with different parameters. It can be also used for different forward-feed current decoupling vector control systems based on flux observation. It reduces the development time of new products and has practical value.
