2、es) Directed by: Professor Li Yaohua Abstract The propulsion control system (PCS) is one of the four subsystems of the Maglev vehicle. The propulsion control theory with field-oriented control (FOC) is the key technology

3、 of the propulsion control system. In this paper, the characteristics of Maglev vehicle propulsion control system with FOC are deeply studied and analyzed. Firstly, the function and structure of the Maglev PCS is analyze

4、d. According to the running performances of long stator synchronous motor (LSM), and refering to the FOC methods of rotating synchronous motors, the LSM FOC theory is studied, and the mathematical models of the Stator FO

5、C, Air-gap FOC, and Rotor FOC theory for Maglev vehicle PCS are developed. The mathematical model of the LSM, the converter, the control system, running resistance characteristics, and the mechanism system with the rotor

6、 FOC control is established in the paper. The simulation parameters and the propulsion performances of Shanghai Maglev line are calculated, and the simulstion results are compared with the experimental results. Finally,

7、The static and dynamic mathematical model of the Maglev vehicle with three kinds of FOC methods are analyzed and established. The effect of the motor parameters (the stator length, the number of the vehicle), the running

8、 velocity, the feeding cable impedance on the PCS performance of Maglev vehicle is calculated and analyzed. The features of the three kinds of FOC methods for Maglev PCS are compared. Keywords: high-speed magnetic levita
