双闭环无刷直流电机驱动电路的设计与实现
资料介绍
在对无刷直流电动机控制系统的发展及应用综述的基础上，介绍了无刷直流电动机的结构和工作原理，给出了其数学模型，并重点分析了无刷直流电机控制技术中简单易用且鲁棒性较好的PID控制算法。对无刷直流电动机控制系统的硬件和软件设计做了详细论述。该电路是基于微芯公司的电机驱动电路专用驱动芯片DSPic30f4011而设计开发的．其中主体电路架构包括电源电路，三相逆变桥电路、转速闭环、电流闭环、线电压闭环和保护电路等。系统的软件设计中，主要包括微控制器的初始化程序、开环起动、换向控制、电流、速度采样时刻控制等。
The structure and working principle of brushless DC motor are introduced in this paper based on summarization of development and application of brushless DC motor control system. The mathematical model is given. The PID control algo- rithm which is easy to use and robust in brushless DC motor control technology is analyzed emphatically. The hardware and soft- ware design of brushless DC motor control system is described in detail. The circuit was designed on the basis of the special drive chip DSPIC30F4011 used in motor drive circuit manufactured by Microchip. The principal circuit architecture includes power supply circuit, three-phase inverter bridge circuit, rotate speed closed-loop, cu...
