| 摘 要： | 提出了采用现代最优控制理论与经典控制理论协调配合的方法，按ＭＵＬ－Ｆ－８７８５Ｃ品质规范要求，设计了Ｊ７Ｌ飞机纵向电传系统控制律。文中针对原型机某些缺陷采用陷模型跟踪最优二次型方法，设计ＦＢＷ纵向基本控制律，并用常规方法设计动态补偿器，指令通道等环节，从对该机主要飞行状态的评价来看，均达到了ＭＩＬ－Ｆ－８７８５Ｃ规范的一级飞行品质要求，由此可见，这种协调设计方法，对飞行控制系统的设计具有较大的潜力

| Abstract: | This paper designed the control law of the longitudinal Fly- BY- Wireabout J7L aircraft by connecting mordern control theory with classical control theory. The first, natural specific property of J7L aircraft was analyzed; Against its some defectthe basic control law of the longitudinal Fly-By- Wire was designed by using the im-plied model-following LQ optimal method.In addition,conventional methods are usedto design the dynamic compensator,forward command path and so on. The evaluationof some main fly states to J7L aircraft shows that all these states satisfy the requirementof level 1 qualities of MIL-F-8785C. This shows that coordinative design methodhave a great deal of potentiality and certain practical values. |
