Process given signal correction method and device of engineering steepest control system

The invention discloses a process given signal correction method and device for an engineering steepest control system, and the method comprises the steps: inputting an obtained process given signal of the engineering steepest control system into a negative proportion arithmetic unit, so as to enable the negative proportion arithmetic unit to output a negative proportion arithmetic signal; inputting the negative proportion operation signal into a six-order inertial filter to enable the six-order inertial filter to output a six-order inertial filtering signal; inputting the six-order inertial filtering signal into a first-order inertial filter, so that the first-order inertial filter outputs a first-order inertial filtering signal; inputting the six-order inertial filtering signal to a minuend end of a subtractor, and inputting the first-order inertial filtering signal to a subtrahend end of the subtractor, so that the subtractor outputs a subtraction signal; inputting the subtraction signal and the process gi
