步进电机反馈控制系统
1)基本要求与提示 (难度系数1.0)
利用利用8255 输出脉冲序列，控制BA,BB,BC,BD 脉冲，经放大后驱动小型步进电机，达到使
电机定速运转之目的.。控制过程采取开环与闭环两种方式实现：
（1）按指定速度控制输出实现开环转速变化；
（2）按指定速度控制输出实现闭环转速变化,闭环控制根据偏差增减输出(固定值或与偏差成比例,类
似于积分调节)；

（3）速度参数可选择通过实验装置上的可变电位器和键盘实时修改（调整）。
（4）利用转速脉冲检测电机实际转速,并在6 位8 段数码管上显示速度,偏差和设定, （V=,E=,S=XXX）
显示内容的切换利用按键。（允许断开控制回路，观察控制效果）
2） 设计提示
步进电机驱动原理是通过对每相线圈中的电流的顺序切换来使电机作步进式旋转。驱动电路由脉冲信
号来控制，所以调节脉冲信号的频率便可改变步进电机的转速。
如图F10.2 所示：本实验装置使用的步进电机用直流＋5V 电压，每相电流为0.16A，电机线圈由四相
组成：即：φ1（BA）；φ2（BB）；φ3（BC）；φ4（BD）
