Study On Three Level Inverter Vector Control System

The project is based on electric induction motor for electric vehicles. Use the indirect rotor field oriented control of a control program as an electric car motor controller. Depth and detailed analysis of the asynchronous motor vector control system for the actual characteristics of the electric vehicle and studies. Detailed design method for asynchronous motor vector control system of electric vehicle applications.Due to the complexity of the system control algorithms, based on DSP TMS320F2808DSP controller and the asynchronous motor vector control algorithm, the project designed to function in accordance with its implementation divided into a number of relatively independent module, using structured programming methods and stages of trial debugging methods; After nearly two years of research and development, based on vector control technology, electric vehicles traction conditions operating point of the motor and controller. The operating point of the brake operating conditions in the laboratory motor test testing bench and electric practical car on the train, and meet the design requirements.
