该程序是本人用AVR ATtiny13写的的一个只用4个IO口驱动两相四线制步进电机的程序，还可以控制转动的上下限（祥见程序屏蔽部分）对使用两相四线步进电机的初学者来说无疑是一笔珍贵的学习资源，对要求以最低成本驱动两相四线步进电机的使用者来说，更是提供了一个有利的参考。推荐！(I use the program is written in AVR ATtiny13 a four IO only I drive two-phase four-wire stepper motor program, but also can control the rotation of the upper and lower limits (祥见shielding part of the procedure) on the use of two-phase four-step beginners into the motor is undoubtedly a valuable learning resource for the lowest cost drive requires two-phase four-wire stepper motor users are provided a favorable reference. Recommended!)

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,...).)
