论文摘要
提出了一种新型的设定会员方法，以估计具有未知和结合的外源输入的动态系统的状态，提出了一种新型的设置会员方法，以监测受到不确定性的安全关键系统的需求。所提出的方法将系统分解为可观察到的不可观察的子系统，在该子系统中，未知的输入观察者和椭圆形设置成员观察者是为每个子系统设计的。讨论了提出的集合估计的界限条件，并使用说明性示例对提出的集合会员观察者进行数值测试。
Motivated by the increasing need to monitor safety-critical systems subject to uncertainties, a novel set-membership approach is proposed to estimate the state of a dynamical system with unknown-but-bounded exogenous inputs. The proposed method decomposes the system into the strongly observable and weakly unobservable subsystem in which an unknown input observer and an ellipsoidal set-membership observer are designed for each subsystem, respectively. The conditions for the boundedness of the proposed set estimate are discussed, and the proposed set-membership observer is also tested numerically using illustrative examples.
