基于模糊控制理论的无人机飞控系统设计

Unmanned Aircraft Fly Control System Design Based on Fuzzy Control Theory

由于无人机数学模型中6个气动系数的各个导数是高度和马赫数的一维或二维函数,使用常规飞控系统的无人机控制器结构复杂,控制效果较差。为了解决以上问题,文中提出了基于模糊控制理论的无人机飞控系统设计,并且进行了仿真。仿真结果表明,基于模糊控制理论的无人机飞控系统控制效果优于常规控制器,它也说明模糊理论在无人机飞控系统中有很好的应用前景。

As six pneumatic coefficients＇ derivative of unmanned spacecraft＇s mathematic model is one-dimension or twodimension function of height and Mach number. The unmanned spacecraft＇s controller employing conventional flight control is complex, meanwhile the effectiveness is bad. In order to solve such problems, the article brings forward unmanned spacecraft flight control employing fuzzy control method and emulates it. The simulation result shows that the effectiveness of unmanned spacecraft controller employing fuzzy control method is better than conventional controller,it also indicates that fuzzy theory can apply to unmanned aircraft fly control system.
