在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。它具有原理简单，易于实现，适用面广，控制参数相互独立，参数的选定比较简单等优点；而且在理论上可以证明，对于过程控制的典型对象──“一阶滞后+纯滞后”与“二阶滞后+纯滞后”的控制对象，PID控制器是一种最优控制。PID调节规律是连续系统动态品质校正的一种有效方法，它的参数整定方式简便，结构改变灵活（PI、PD、…）(In process control, the PID controller (also called PID regulator) controlled by deviation ratio (P), integral (I) and differential (D) is one of the most widely used automatic controllers. It has the advantages of simple principle, easy realization, wide application, independent control parameters, simple parameter selection, etc. It can also be proved theoretically that PID controller is an optimal control for the typical object of process control - "first-order lag + pure lag" and "second-order lag + pure lag". System. The regulation rule of PID is an effective method for dynamic quality correction of continuous system. Its parameter setting method is simple and its structure is flexible (PI, PD,...).)

本例程实现一个简单的AM FM收音机功能。本程序无显示，通过串口打印信息。程序固定预设了武汉地区的FM电台和AM电台列表。上电缺省是FM模式，通过按键可以切换AM和FM。(This routine implements a simple AM FM radio. The program no display, print information through the serial port. Program fixed preset FM radio stations in Wuhan and AM station list. On power-up default mode is FM, AM and through the key switch FM.)
