[Abstract]:Faced with the shortage of resources and environmental protection, the development of electric vehicles has become the mainstream trend of automobile industry. As the core of electric vehicle, motor drive system plays an important role in the performance of electric vehicle. In this paper, the drive motor control scheme of electric vehicle based on Infineon Tricore motor controller is proposed, and the drive control of permanent magnet synchronous motor based on this controller is realized. This article is in Xi'an city science and technology bureau project: small pure electric coach car power system matching and optimization design (project number: cx12494) and the central university innovation team project: plug-in small pure electric field coach car key technology Research (Project No.: 2013G 3222004). In this paper, the development status of electric vehicle motor controller at home and abroad is systematically studied, the characteristics and classification of electric vehicle motor drive system are analyzed in detail, and the mathematical model and vector control theory of permanent magnet synchronous motor are systematically studied. The research content of Infineon Tricore motor controller includes the realization of hardware function and software function of motor controller. In the aspect of hardware function, the selection and design of current and position sensors are included in addition to the research on the main modules of motor controller. The software development includes the design of development tools and software algorithm. With the help of Infineon Tricore permanent magnet synchronous motor controller, the motor control algorithm is designed to realize the speed regulation control of permanent magnet synchronous motor of electric vehicle. In the MATLAB/SIMULINK environment, the vector control model is built, each module is studied, and the double-motor drag model is built, and the control algorithm is verified by simulation. Through the experimental verification of Infineon motor controller and control algorithm, the feasibility and practicability of vector control technology in motor drive control of electric vehicle are verified under the no-load and loading test conditions of the motor. The feasibility of Infineon Tricore motor controller in PMSM speed control is also proved.
