Modified generalized predictive control algorithm

Aiming at solving the problem of big calculation amount of generalized predictive control(GPC) algorithm itself and not consideration to both rapidity and over modulation,a modified algorithm was advanced.Firstly the basic algorithm of generalized predictive control and a new-fashioned algorithm were introduced,including the fundamental theory and the good and bad points.Then by means of certain mathematical analysis a modified algorithm was offered.At last the Matlab simulations to the three algorithms were carried on to compare the static error.The result indicates that the modified algorithm not only reduces the calculation amount but also controls the over modulation well and gives dual attention to rapidity simultaneously.
