摘    要:设计观测器的目的是利用系统的输出量和输入量来重构状态。在设计观测器过程中,除了要求状态估计值x渐近逼近真实值x外,不希望两者间有一个合理的衰减率,而这与观测器系统的极点位置密切相关,精确配置极点的观测器难以满足其它期望性能指标约束,将观测器系统矩阵的极点配置于一指定区域内,可使极蹼的选取获得较大的自由度。该文对线性定常系统的降维状态观测器区域极点配置问题进行了研究,通过对观测器增益阵的分析设计,给

关 键 词:线性系统 极点配置 降维状态观测器 观测器

Abstract:The aim of designing observer is to rebuild the states through input and output. A suitable decay rate which is relevant to the situtation of poles from estimated to real x is important. However, observers with accurate pole placement often can not satisfy other performance indices. In this paper, the regional pole assignment of reduced order state observer is discussed. It gives the unified algebraic parameterization of these kinds of reduced order state observers and the fundamental guidlines to design state observer so as to suit for multiobjective performances.
Keywords:linear systems   pole allocation   decay rate  reduced order state observer
