基于矢量控制的电动自行车控制器设计
Design of electric bicycle controller based on vector control
摘要
Abstract
The demands of electric bicycle transmission system for energy saving and noise reduction are increased. In com-parison with the traditional brushless DC motor driven in the 120° square wave drive mode with conduction in pairs,the perma-nent magnet synchronous motor in the mode of vector control has the advantages of low noise and low energy efficiency. Under the premise of satisfying the basic functions,a low-cost hardware of the controller was designed. The basic principle of the seven-step space vector pulse width modulation(SVPWM)that two zero vectors are utilized alternately and single-resistance sampling stator current reconstruction,and the software implementation of the electric bicycle′s basic functions are described. The control-ler was verified on the experiment platform based on STM32F031C6T6. The experimental results show that the vector control sys-tem can enhance the performance of the electric bicycle drive system greatly,and has higher cost performance than the square wave controller.关键词
