从整定方式来分，调节器有普通型和电压整定型两种。普通型和电压整定型调节器的基本组成是相同的，区别只是在参数整定电路方面。在普通型调节器中，参数的整定只能就地进行，可以用调整电位器的阻值或用波段开关切换电阻或电容来改变整定参数;在电压整定型调节器中，整定参数P, TI、TD受外给电压控制，因此可以做到远程整定、第三参数整定、自整定等。下面围绕普通型PID调节器进行分析讨论。
PID调节器的组成可以用图4-36所示的方框图表示。调节器主要由翰人电路、运算电路和输出电路三部分组成。但在有的调节器中，输出电路与运算电路是一个不可分荆的整体。此外，还可能附带有指示电路、手动操作电路及限幅电路。指示电路分为偏差指示、给定值与输入值的全刻度指示两种。
