非线性自适应控制在无尾飞控系统中的应用

无尾飞机是新型飞机的研究方向,由于其没有尾翼甚至机身,导致横侧向模态自身以及横侧向模态与纵向模态之间存有强耦合非线性特性。将非线性自适应控制应用到无尾飞控系统中,结合MATLAB的仿真工具,对无尾飞机模型进行实时仿真,得到了相应的仿真曲线。通过对仿真曲线的分析,验证了该控制方法在无尾飞控系统应用中的可行性。

Application of Nonlinear Self-adaptive Control in the Flight Control Systems of the Tailless Aircrafts

The tailless aircrafts are regarded as a developing way of the new type aircrafts,which have non-linear characteristic of strong coupling in the lateral-directional mode and in between lateral-directional mode and longitudinal mode due to lack of empennage and even fuselage.The nonlinear self-adaptive control method is applied to the flight control systems of the tailless aircrafts,and the simulation tool of MATLAB is used at the same time.With the real-time simulation to the tailless airplane model,the relevant simulation curves have been acquired,and the result analyzed by the simulation curves validates that this control method is feasible to the flight control systems of the tailless aircraft.
