Research on Observer-Based Vector Control Strategy for Battery Vehicle Drive System
摘要
The main research content of this paper is as follows: Firstly, the observer-based MTPA vector control strategy is adopted, and the observer is used to improve the anti-interference ability of the system. On the Matlab simulation platform, the simulation model of the drive control system of hydrogen fuel cell vehicle is constructed, and the test scheme of the drive control system of hydrogen fuel cell vehicle is designed. The simulation results show that the design of the hydrogen fuel cell vehicle drive control system in this paper can meet the requirements of hydrogen fuel cell vehicle drive response time, speed control precision and other technical indicators at start-up, acceleration and deceleration, and constant speed operating conditions. And in the working condition, the motor can quickly follow the given value, and has a strong anti-interference ability; Relative to the stable value of stator current, the speed and torque of the motor can maintain high stability, the speed of the motor, torque and stator current fast follow and strong anti-interference ability, to ensure the stable operation of the system.
