首先，介绍了基本DC．DC变换器的拓扑结构特点和数学建模方法，并用Matlab进行了仿真，为后面基于DSP数字PID控制的DC．DC变换器的研究与设计建立了理论基础。其次，分析了常规PID控制理论，阐明了结合系统函数设计PID幸b偿器的实现过程，以及从S域中实现常规PID数字化的方法并给出了利用DSP实现数字PID控制器的具体策略。第三，结合数字PID控制理论的分析，以Buck变换器为例，完成了基于DSP数字PID控制的Buck转换器的实际电路以及控制程序设计，并制作了试验样机。最后，试验样机测试和结果分析。实验结果表明，本文使用的基于定频PWM技术的数字PID控制方法的开关

网上很多关于bootloader的例程，一直没找到利用U盘更新的，这里提供一个通过U盘更新APP程序的例程，测试环境是ALIENTEK STM32F407开发板。 其中值得注意的是U盘中断问题，更新完程序后要及时关闭中断跳转到APP后才能正常运行，否则可能会死在上有中断未处理的地方。
