A design scheme of boiler steam temperature control system adopting serially connected multi-capacitance and small inertia link mode to realize the full-scale compensation feed-forward control has been put forward.Result of emulation shows that the effectiveness and robustness of the feed-forward control is related to the time constant of serially connected multi-capacitance and small inertia link

the steps of multinomial expression for the denominator of said link should be greater than that of the numerator.The full scale feed-forward control method with serially connected multi-capacitance and small inertia link overcomes the realizability problem of the full-scale compensation feed-forward controller.
