控制系统中的增益、补偿增益、补偿偏置分别是什么意思呢 ...? 印象中,CS3000系统中PID调整画面, 没有GAIN参数,有补偿增益CK和偏置基数CB. 补偿分为输入补偿:CVn=PVn+CK(VN+CB) The input compensation is used to improve the controllability of a process with a long dead time, by subtracting from the input signal the signal from the Dead-Time Compensation Block (DLAY-C) to perform PID control computation (Smith Dead Time Compensation). 和输出补偿MVn=MVn0+CK(VN+CB). The output compensation is used for feedforward control that adds the feedforward signal to the control output signal, or for non-interacting control that adds the output signal from the interacting loop to the control output signal. "好像没有什么用" 可能是根本就没有组态"补偿".你查一下BIN端子是否有端子连接或VN是否有数据连接.如果都没有.VN=0,则CK*(VN+CB)=0.自然没作用.不过要注意CK从1给到最大值10.如果真接有补偿,工艺过程参数可能不对了.查看更多
