PROBLEM TO BE SOLVED: To provide a feedback control system and method capable of realizing smooth and stable control by preventing any overshoot or hunching when the setting of a target value is rapidly changed. SOLUTION: When a set target for an object to be controlled is changed, a change processing means 200 increases or decreases an intermediate target value Tr2 in order to make it gradually close from an initial set target Tr0 to a new set target Tr until the detected output of the state quantity of the object to be controlled reaches the new set target Tr. Then, the intermediate target value Tr is defined as a control input Tr1, and a deviation valueΔT between the control input Tr1 and the detected output of the object to be controlled is calculated, and the control signal is compensated according to the deviation valueΔT by a compensating means 85.
