【摘要】 针对多操纵面布局飞机,提出一种基于Kriging建模技术和鲁棒自增益调参控制器设计技术的大包线飞行控制系统设计方法。通过采用力矩控制形式,使调参控制器的输出为三轴所需力矩系数,从而便于采用力矩控制分配技术来发挥冗余操纵面的潜力,并提高系统鲁棒性;在设计使系统性能指标最优的控制律时,通过建立控制系统性能参数的Kriging近似模型,避免了多次进行耗时的控制器设计,提高了设计效率。更多还原

【Abstract】 A design method for the large-envelope flight control law was proposed based on the Kriging modeling technique and robust gain-scheduling design theory,which is suitable for the airplane with multiple control surfaces.Through the moment control form in control law design,the controller’s outputs become the required moment coefficients in 3 axes,so it’s easy to make use of the redundant control effectors and improve the robustness with moment control allocation technique.When designing the control law which optimizes the system’s performance,many times of time-consuming design processes are avoided by means of constructing the control system’s Kriging model,so the design efficiency is improved.更多还原
