综合飞行/推进系统的μ控制研究

Study on the μ Control of Integrated Flight and Propulsion System

在飞行推进系统设计中研究了综合飞行/推进系统小偏离动态模型建立的方法,并得出了相应状态的综合飞行/推进系统的状态空间模型。对μ控制理论的控制及基本原理进行了分析。接着根据各项要求,选取了加权函数矩阵。构建了相应的广义受控对象,并设计出一个用于摄动对象的μ控制器。将所设计的控制器联接综合飞行/推进系统构成闭环系统,针对各项性能要求,进行仿真。通过仿真验证表明,根据μ控制理论所设计的控制器对综合飞行/推进系统的控制效果良好,达到了提出的性能要求,有一定的工程应用价值。

A dynamic model of a small deviation in the integrated flight/propulsion system is studied. The state - space model of corresponding state of integrated flight/propulsion system is obtained. And on the controling and the basic principle of μcontrol theory thought are analyzed. Then to meet the weighting function matrix is selected to meet the requirements. In constructing the generalized controlled objects, a μ controller is designed for the perturbation target, and quality requirements are taken into account. Finally, the designed controller connected to the integrated flight/propulsion system constitutes a closed - loop system, in view of the performance requirements for simu- lation. By simulation, the controller of the integrated flight/propulsion control system designed on the basis of μ control theory works well. It can achieve the proposed performance requirements and has a certain engineering application value.
