基于DSP的混合动力汽车电驱动控制系统设计

对混合动力汽车(HEV)电驱动控制系统进行了设计,采用转速、转矩双闭环控制,实现了恒转矩启动和恒功率运行。整个电驱动控制系统包括电源模块、逆变模块、控制模块、驱动模块、系统安全检测模块、CAN通讯模块等主要部分,可以实现电动发电和制动能量回馈功能。为了验证所设计系统的有效性,研制了一个小功率试验平台,该平台以TMS320LF2407A型DSP为核心器件,基本实现了HEV所需的大部分功能。

Design of Motor Drives System for HEVs based on DSP

A motor drives system for hybrid electric vehicle(HEV) is presented.The control system has speed and torque dual closed loops,which can realize the big torque starting and constant power running.The whole electrical drive system including power source module,power inverter module,control module,drive module,system security detect module,CAN communication module etc.are mounted on the same hardware,just by designing the software can realize generator and electromotor function.In order to validate the design,a small-power BLDCM drive system is designed,which has selected the DSP of TMS320LF2407 as the core chip.The small-power BLDCM drive system contains all the functions required by the HEV.
