Design and implementation of invertor energy regeneration system based on tms320f 2811的变频器能量回馈系统的设计与实现
2.
Regard how to structure the control system of sensorless bldcm with dsp - tms320f240 as the centre in this paper , the detailed argumentation course of the motor startup , bemf terminal voltage measurement and control strategy is given out , give and pay concrete details for the software and hardware realization and experimental result . in order to treat the bldcm control system with dsp clearly , the full paper divides into six chapters altogether : chapter one , introduceing the development course , the structure characteristic and operation principle , etc . of bldcm in the introduction ; chapter two , directed against the startup issue of bldcm , the chapter give and publish the rotor measure pulse orients technology for motor startup in detail ; chapter three , proceed with mathematics model of the bldcm , expounding the control schemes ; chapter four , two important devices introducing : dsp ( 240 tms320f ) and power invertor control chip ( ir2131s ) ; chapter five , give and publish the detail of hardwares of control system ; chapter six , by ccs ide of ti , realize the control schemes in the front chapters with software , offere the procedure flow chart of main subroutine and some key place of programming , the experiment result in addition 全文共分六章:第一章、绪论中介绍了bldcm的发展历程、电机本身的结构特点和工作原理等;第二章、针对五位置传感器bldcm的起动问题,文中详细给出了检测脉冲转子定位起动技术;第三章、从电机的数学模型入手,详细论述了反电动势端电压法和系统的控制策略;第四章、介绍了硬件实现中的两个重要器件: dsp ( tms320f240 )和功率管逆变器控制芯片( ir2131s ) ;第五章、详细给出了控制系统的硬件实现细节;第六章、利用ti提供的ccs集成开发环境,将前面章节的控制方案用软件加以实现,给出了主要部分的程序流程图和一些编程要点以及实验结果。
