摘　　要：应用状态反馈预测控制算法 ,对带有耦合、不确定性的油田联合站油水分离控制过程进行分析 ,给出基于状态反馈的电脱水系统的多变量适应式SFPC算法 ;基于Lyapunov稳定性理论 ,对时滞过程进行分分析 ,推导出多变量线性时滞系统的时滞独立稳定充分条件方程式。在此基础上 ,给出几个判定线性时滞系统独立稳定的简单判据。讨论时滞系统的指数稳定性 ,给出系统具有任意指定收敛速度指数稳定的充分条件及相应的推论。Based on state feedback predictive control (SFPC) algorithm,the oilfield combination station oil water separation process with time lag and uncertainty has been analyzed.The multi variable SFPC algorithm of electric dewater systems was given.Based on the theory of Lyapunov stability,a sufficient condition of delayed independent stabilization of delayed system is derived.Another representative of the theory is also given.Based on this,several simple criterions of judging linear time lag delayed system independent stabilization are presented.The exponential stability for delayed system is discussed too,and the exponential stability sufficient condition with specified decay rate and its corresponding corollaries are given.
