[Abstract]:With the consumption of energy and the deterioration of the environment, the production and research of electric vehicles under heavy pressure has developed rapidly. As one of the three key technologies of electric vehicle, motor and its control have been paid more and more attention. This paper is based on the brushless DC motor controller in the market. According to the development demand of electric vehicle, the controller of brushless DC motor with energy feedback is developed successfully by further function enrichment and performance optimization. The basic structure and principle of brushless DC motor (BLDCM) are deeply understood. The working state of brushless DC motor (BLDCM) when it is in electric operation and feedback braking is analyzed emphatically. The modulation mode of power MOS tube under different working conditions is determined and the control scheme is worked out. A double closed loop speed regulation system with fuzzy and Pi in electric operation is designed. The speed loop adopts fuzzy control, the current loop adopts Pi control, which has the characteristics of faster response and better real-time performance. The peak value of feedback current is limited to a certain extent and the charge safety of battery is ensured. The function and performance requirements of brushless DC motor controller for electric vehicle are defined. Under the guidance of the control scheme, the hardware circuit of each module is designed with Protel 99SE software. Using the idea of integrating the integrated module and the discrete components, the cost of the controller is reduced under the premise of guaranteeing the reliability of the hardware system. The main control circuit, the power supply circuit and the signal isolation circuit are mainly used. The power circuit and the detection circuit are composed of five parts. Based on this hardware, using the modular program compiling idea and using Keil MDK software to design a set of complete master control MCU software solution, the fuzzy control algorithm and Pi control algorithm are realized, and a double closed loop speed regulation system is formed. The energy feedback during braking is completed and the feedback current is limited, the detection and protection of current and voltage are strengthened, the function of controller is improved and its performance is improved. According to the requirements and results of the hardware and software design of the controller, the 57BL55 motor and the 80BL130 motor test-bed .57BL55S motor test stand are built for debugging, the hardware feasibility of the designed brushless DC motor controller is tested, and the program debugging is carried out. The 80BL130 motor test bench is used to test the reliability of the designed brushless DC motor controller software and hardware, and the dynamic test is carried out to improve its performance. The experimental results show that the controller of energy feedback brushless DC motor designed in this paper is stable in starting and fast in speed regulation, and the feedback braking is realized, which meets the requirements of its function and performance.
