In view of the complexity and low efficiency in the process of conversion from simulation to the appli- cation by conventional vector control algorithm, this paper studied the simulation and application of vector con- trol algorithm by combining software-in-the-loop simulation which includes control chips in the ring with the dsPACE hardware-in-the-loop simulation. This method omitted the program transplantation and the physical verification process of the application and hardware platform of conventional algorithm simulation, which would realize the seamless connection from the simulation to the application and improve the development efficiency of the algorithm. Finally, this paper presented two kinds of simulation results of the vector control algorithm, show- ing that the proposed method can effectively complete the research on algorithm development and the application of the algorithm on the hardware platform.
