一个正系统是一个动力系统，如果它的轨迹是从状态空间的非负正交线出发，那么它的轨迹就保持在该正交线上。研究了一类分区系统的观测器设计问题。首先给出了正观测器存在的一个充分必要条件，修正了文献中的一个结果。通过放松观测器结构，提出了一种新的单输出系统正线性观测器的设计方法，该方法只需要满足可检测性条件。文中还提供了一些实例来说明这一理论
A positive system is a dynamic system whose trajectory remains in the nonnegative orthant of the state space if it is originated from the orthant. The observer design problem for compartmental systems which are also positive systems is studied. At first, a necessary and sufficient condition on the existence of a positive observer is provided which corrects a previous result in the literature. By relaxing the observer structure, we propose a new design method of positive linear observer for single output systems which requires only the detectability condition. Academic examples are provided to illustrate the theory
