摘    要:以基于前掠翼布局及翼身融合一体化技术设计的W型无尾飞机为被控对象,采用线性二次型高斯/回路传输恢复LQG/LTR(Linear Quadratic Gaussian with Loop Transfer Recovery)多变量鲁棒控制方法完成了飞机横航向控制设计.该方法解决了由于该特殊构型导致的本体不稳定,以及运动模型的不确定性、随机干扰下控制系统可能出现的不稳定和控制精度不够的问题.系统仿真结果表明,控制系统实现了横航向指令的精确跟踪,不但具有良好的鲁棒性,而且调节性能良好,满足W型无尾飞机横航向控制设计的要求.

关 键 词:W型无尾飞机  线性二次型高斯/回路传输恢复  不确定性  随机干扰  鲁棒性

Abstract:With the W-shaped tailless aircraft which is based on forward-swept wing configuration and the integrated design of blended wing-fuselage took as a control object, by the linear quadratic Gaussian with loop transfer recovery (LQG/LTR) method of multivariable robust control, the aircraft′s lateral-directional control system was designed. The inherent instability of this special configuration, the problem of control system′s instability and lack of control accuracy which may be caused by the aircraft motion model′s uncertainty and random disturbance were solved. The simulation results show that the lateral-directional command can be followed accurately, and the control system not only has good robustness, but also has good regulating process, which satisfy the lateral-directional control design requests of the W-shaped tailless aircraft.
Keywords:W-shaped tailless aircraft  linear quadratic Gaussian with loop transfer recovery  uncertainty  random disturbance  robustness
