摘要: 通过分析附加有界扰动不确定系统的开环最大最小模型预测控制(OLMMMPC)的可行性和稳定性, 指出一般情况下OLMMMPC问题初始可行但未必一直可行, 进而闭环系统也未必稳定, 并给出了该问题只要初始可行就有闭环系统稳定的一个充分条件及OLMMMPC问题的一种改进算法, 该算法保证只要问题初始可行闭环系统就稳定.

Abstract: We considered the feasibility and stability of openloop minmax model prediction control (OLMMMPC) for systems with additive bounded uncertainties. It is concluded that the OLMMMPC may not be feasible and stable if it is only initially feasible. A sufficient condition of the OLMMMPC that ensuresits feasibility and stability is given. Then we proposed an improved OLMMMPC algorithm which guarantees robust stability of the closed loop system once the problem is initially feasible.

Key words: additive bounded uncertainty, predictive control, feasibility, stability
