Sam Nazari, Bahram Shafai, Amirreza Oghbaee

AI总结:

本文首次提出正线性系统正未知输入观测器设计方法,通过LMI正稳定方案和设计矩阵广义逆的正性条件,解决正系统在存在未知输入时的状态估计问题。

摘要:

正系统是重要的动态系统类别,其响应在正初始条件和正输入下保持非负性。尽管已有正观测器设计,但无法在存在未知输入或扰动时估计状态。本文首次尝试为正线性系统设计正未知输入观测器(PUIO)。观测器参数的结构约束使设计任务复杂,但通过利用LMI正稳定方案,并对特定设计矩阵的广义逆的正性施加条件,提供了一种可靠的PUIO设计方法。

英文摘要:

Positive systems are important class of dynamic systems with impressive properties. The response of such systems to positive initial conditions and positive inputs remain in the nonnegative orthant of the state space. Although positive observers have been designed for positive systems, they are unable to estimate the states when unknown inputs or disturbances are present in the systems. This paper is a first attempt to design positive unknown input observers (PUIO) for positive linear systems. The structural constraints on observer parameters make the design task cumbersome. However, with the aid of a positive stabilization scheme via LMI and by imposing conditions on positivity of the generalized inverse associated with a certain design matrix, we provide a reliable procedure for the design of PUIOs.
