系统硬件组成直流电机测控系统如所示。本系统是以Cygnal C8051F020为核心所组成的闭环实时测控系统，是一个典够实现速度预置、转速显示，并能对转速进行精确测控。

　　霍尔测速电路产生的采样脉冲送外部中断，通过计数器进行计数，从而算出转速。将这个转速值与预置转速值比较，得出差值。C8051通过对该差值进行PID运算，得出控制增量，再由C8051输出控制参数，由PWM电路改变电机两端的有效电压，最终达到控制转速的目的。

　　直流电机测控系统原理图键盘和显示电路采用了串行接口的7279控制电路。

　　在功能键盘上输入控制命令，电机转速显示在七段码显示器上。

　　PWM控制器方向为计算机测控技术。

　　p%Ms控制器由pwM波开形发生器和pwm延时保护t与功放电路组成。系统中测速部分使用了定时器T0，如果PWM波形发生也由C8051产生将会加大软件的任务，从而影响整个系统的实时控制效果。因此由外部电路产生PWM的波形，而C8051只提供控制参数来改变脉宽占空比，达到电机转速的变频调控。PWM波形发生器如所示。

　　输出脉冲的周期和频率可以计算出转速。为了提高对电机转速测量的精度，可以在电机转盘上均匀固定多块磁钢，电机每转一圈，霍尔传感器将会产生多个脉冲，通过软件计算可以精确测量电机转速。

　　由于霍尔传感器输出的脉冲波峰小、波形边沿不完整，采用施密特触发器电路对脉冲整形后输出到C8051外部中断INTO，施密特触发器输入输出波形如所示。

　　u.本PWM波形发生器中U1是一个10位的计数器，计数器的时钟输入端CP接C8051晶振的XTAL2端。本系统中采用的主频为12MHz的晶振，经过U1分频后得到PWM波形频率级联。U2的人>Bout端接一个过零比较器，其输出为PWM波，PWM波的脉宽可以通过从P0口输出数值改变。
