摘　　要：工程上飞行控制律一般基于传统的经典控制理论设计,而且缺乏不确定性存在情况下对控制律性能的系统考查,逐渐不能适应现代飞行控制系统的发展。针对现代飞行控制系统中广泛存在的不确定性,进行控制律评估与确认技术方法研究,提出了进行现代飞行控制律评估与确认的内容、步骤、适用的先进评估方法和评价准则,并且构建了相应的可视化、自动迭代仿真环境。对我国在此领域的研究具有积极的意义。In engineering, flight control laws were usually designed by traditional classical control theories. Moreover, it also lacked a systematical validation and verification process for the designed control laws with all kinds of uncertainties. Due to this presentation, some new ideas and methods should be proposed to meet the requirement of modem flight control system development. Based on the analysis of modern flight control law design, the advanced approaches for clearance techniques were studied while there are different uncertainties with aircraft modeling. For insufficiency in current methods, some results in the world were analyzed, and the advanced clearance techniques were systematically studied, which presents the contents, steps, methods, and clearance criteria for modern flight control law clearance. Also, the automatically iterative and visualized simulation environment was designed.
