航天员的模糊控制模型及应用展望

本文以航天员控制过程中的思维活动(概念、判断、推理和决断)为基础,用模糊集理论建立了航天员的模糊控制模型,并在地面模拟条件下,用航天员控制飞船时的实验结果说明了模型的有效性。本模型可以描述航天员控制载人航天飞行器(如飞船、航天飞机和空间站等)的控制行为。该模型的建立不仅为航天人—机—环境系统的总体分析、评价和设计提供新手段,而且为模糊控制理论的发展和模糊控制系统的分析、设计奠定了基础。

THE ASTRONAUT'S FUZZY CONTROL MODEL AND PROSPECT FOR ITS APPLICATION

This paper proposes a Fuzzy Control Model (FCM) for the astronaut by means of fuzzy set theory on the basis of human thinking activities (concept, judgement, inference and decision). In order to demonstrate the efficiency of the model the experiment results of astronaut's controlling spacecraft are given under the condition of the ground simulation. This model can be used to describe the control behavior of astronaut's controlling manned vehicle (such as spacecraft, shuttle and space station). The establishment of this model not only provides a new way for the analysis, evaluation and design of the space man-machine-environment systems, but also can lay a foundation for the development of fuzzy control theory as well as analysis and design of fuzzy control systems.
