<p>图三所示TEC热闭环中为2Hz的交叉补偿的例子。尽量选择高阻值的R3以使积分电容C2尽可能小。然而这种方法也有弊端，它会使得PID的增益变小。因为我们必须在70mHz插入一个零点，我们使用关系：</p>

<p>前文已经说过，FZ1 = 70mHZ，如果选择R3 =243kΩ，那么C2 就应为9.36μF。我们选择10μF设计。现在我们选择R1 =10kΩ。这使得前端放大器（U2）有足够的增益以减少反射积分器（U1）的错误，同时保持合理的电容器的尺寸。 现在，我们必须插入一个零点以抹去第二个在1Hz的TEC响应曲线极点。因为我们希望得到良好的相位裕度，零插入所需的交叉频率除以至少5或0.4Hz。这给出了一个在交叉频率的一个更好的相位裕度。然后通过放置由R1创建的、至少5倍于交叉频率，或者10Hz的极点终止该零点。这限制了积分器的的增益。 所以，因为： </p>

<p>由于R3 =243kΩ，XC =j79.6kΩ，G = 3.05或9.7分贝。要想对此增益进行全面的分析，就不应忽视R1、R2、C2和C3，此时G = 3.11或9.8分贝，从而验证了我们的假设。现在，我们必须在前端再提供20.3分贝的增益以完成2Hz处的增益交叉。 <br>
前端增益部分有两个功能：它减少积分器U1产生的误差，和采集从热敏电阻传来的温度信息。 由R4、R5和U2（图3）所设定的直流增益需要足够高以防止该误差信号被PID补偿电路消除。由于R4 =10kΩ，R5 =100kΩ，那么前端增益是11或20.8分贝，足以压倒9.7分贝的PID补偿部分。从热敏电阻传来的温度读数以误差信号的形式被传递给PID控制部分。该误差信号表示的是实际温度和所需温度（设定值）之间的差异。U2输出的误差信号可以按照下式计算：</p>
