-
摘要: 本文利用预测误差的历史数据修正系统的预测输出，以抑制模型失配的影响．给出了修正的最小方差调节器和广义最小方差控制器的算法，并分析了所给修正算法能增强系统鲁棒性的机理．仿真结果表明了本算法的有效性．Abstract: In this paper,the historical data of predictive error are used to correct the predictive output of the system.So the influence of unmodelled dynamics can be restrained.The algorithms of correcting minimumvariance controller and correcting generalized minimum variance controller are presented.It is analyzedthat the correcting algorithm can strengthen the robustness of the system.Simulation results show theeffectiveness of this algorithm.
