Stability Analysis of Modified Generalized Predictive Control
改进的广义预测控制的稳定性分析

D. W. Clarke proposed a Generalized Predictive Control (GPC) algorithm in 1,2]. we have propossed a modified control algorithm 3,4]. In this paper, the stability of modified control algorithm 4] is analyzed. The characteristic polynomial of the loop system is simply expressed, its parameters are directly obtained from predictive model parameters requiring no further computation. Its conclusions are still suitable to the analysis of the original GPC algorithm 1,2,5].
