摘要
在对可重复使用跨大气层飞行器(RTAV)进行多学科设计优化(MDO)的过程中,对RTAV姿控子系统的时域仿真是姿控子系统设计和飞行稳定性分析的重要手段。对某RTAV的MDO过程中姿控子系统的Simulink建模与三通道综合时域仿真的方法进行了研究。从理论上分析了建模、仿真过程中遇到的代数循环问题,并针对问题特点提出了解决方案。
The simulation in the time field for the attitude control subsystem of Reusable Transatmospheric Vehicles （RTAV） is an important means for design and analysis of the subsystem during the process of multidisciplinary design optimization （MDO） of RTAV. The methods of modeling and simulation with Simulink to the attitude control subsystem of RTAV in MDO are studied. Algebraic loops occured during the modeling and simulation process are analyzed theoretically, and then a solution to the algebraic loops is discussed. Right results have shown the methods presented are viable.
