Abstract: A method to implement the dynamic simulation for an induction motor vector-control system was investigated. The complete simulation model was created with the help of the graphical toolbox of Simulink, being embedded into C++ program, and was transferred to stand-alone software that can generally, dynamically and visually do kinds of simulations for the induction motor control system. The results show that the model derived by the method is accurate and the software is functional well and easy to use.
