多年来的自控原则

1.设C1和R1并联成Z1，那么？z 1 = r 1 * 1/c 1S/(r 1+1/c 1S)= r 1/(t 1S+1)

其中T1=R1*C1。

2.那么，让C2和R2并联成Z2？z2 = R2 * 1/C2S/(R2+1/C2S)= R2/(T2S+1)

其中T2=R2*C2

3.Z1和Z2是分压电路，即uo/u1= Z2/(Z1+Z2)。

也就是传递函数？uo/u 1 = R2/(T2S+1)/(r 1/(t 1S+1)+R2/(T2S+1))

？= R2 *(t 1S+1)/[r 1(T2S+1)+R2(t 1S+1)]

？= R2 *(t 1S+1)/[(r 1 * T2+R2 * t 1)S+R2+r 1]
