本文介绍了一种以改善飞机大气紊流响应品质为主要目的的控制系统最优控制律的设计方法.该方法以“乘座品质最优”为目标,设计系统的各反馈增益。文章为一架算例飞机设计了最优控制律并作了开、闭环飞机大气紊流响应特性及乘座品质指标的计算、分析与比较.结果表明,所提供的设计方法不仅计算较为简便(与目前国内常用的变反馈参数法(参考文献[1])相比),而且相当有效,确实能在一定程度上改善飞机的大气紊流响应品质.
This paper presents a design method of the optimal control law of the control system with the aim of improving the turbulence response of the aircraft. The objective of this method is to design the optimal gain of the system. In this paper, an optimal control law is designed for an example aircraft and the calculation, analysis and comparison of atmospheric turbulence response characteristics and ride quality indicators of open and closed-loop aircraft are carried out. The results show that the design method provided is not only simple and easy to calculate Compared with the current commonly used variable feedback method (Reference [1]), it is quite effective and can indeed improve the atmospheric turbulence response quality of the aircraft to a certain extent.
