摘要
与传统的航空航天器相比,高超声速飞行器具有建模困难、不确定性大、参数剧烈时变、耦合严重以及异类执行机构等控制难点。针对上述五个方面的研究现状进行综述,首先概括了高超声速飞行器建模研究成果,给出了面向控制系统设计的仿射非线性模型;其次针对不确定性、参数时变和耦合等问题,总结相关控制方法的研究成果;最后,对异类执行机构复合控制问题进行了阐述和总结。
Compared with the traditional aircraft, hypersonic vehicle has difficulties for flight control system design such as the difficult modeling, the large uncertainty, the fast time-varying parameters, the serious coupling and different kinds of actuators. This paper is the overview of the above five aspects : firstly, the research results of the hypersonic vehicle model- ing have been generalized and control-oriented affine nonlinear model has been given. Secondly, the research of control de- sign about uncertainty, time-varying parameters and coupling has been summarized. Finally, compound control of different kinds of actuators has been summarized.
