一、调节器的组成和调节规律的实现方法DDZ-Ⅱ型调节器是 DDZ-Ⅱ型电动单元组合仪表中的一个主要单元。调节器接受变送单元输出的0～10mA 直流电流信号(即被调量信号),将此信号与设定值相比较而得到偏差信号,然后按偏差的大小和变化情况,进行比例、积分、微分运算,给出调节信号,去控制执行器的动作,实现自动调节。调节器的主要品种有比例积分调节器(即 PI 调节 First, the regulator of the composition and regulation of the method of realization DDZ-Ⅱ-type regulator is DDZ-Ⅱ-type electric unit combination instrument in a major unit. Regulator to receive the transmitter unit output 0 ~ 10mA DC current signal (ie, the signal is modulated), the signal is compared with the set value to get the deviation signal, and then according to the size of the deviation and changes in the ratio, integration, Differential operation, given the adjustment signal to control the actuator action, to achieve automatic adjustment. The main varieties of regulators are proportional integral regulator (ie, PI regulator
