英文摘要：
To develop the algorithms control platform which works quickly and conveniently,the technology of the space vector PWM and power conversion is used to construct the speed control system of the asynchronous motor based on dSPACE real-time simulation platform.Firstly,the overall design of the hardware circuit includes the rectifier,the three-phase inverter,the fault output and the three-phase current acquisition circuit.Then the vector control algorithm is simulated and the result of the experimental is analyzed.Finally the closed-loop control system of the asynchronous motor is achieved on the dSPACE semi-physical simulation platform.The results of the simulation and experiment show that the electric motor is running smoothly,when there is a load disturbance in the operation,the asynchronous motor can quickly regain the set speed and the system have good dynamic and steady-state performance.The feasibility of the hardware circuit and control algorithm can be quickly verified and the development time of the project can be effectively shortened on the dSPACE semi-physical simulation platform,in addition,the project＇s cost is saved to a large extent during the design and test period.
