摘　　要：对于倾斜转弯(Bank-to-Turn,BTT)自动驾驶仪而言,侧滑角应尽可能控制在零附近,而抑制快速滚转运动耦合产生的测滑角是实现BTT控制的关键之一。文中首先利用H∞控制理论对俯仰、偏航、滚转三通道进行独立设计,并考虑了模型不确定性因素的影响,设计出鲁棒稳定性较好的控制器,以此为基础,在偏航通道上人为引入一协调指令,以达到抑制侧滑角的目的。该方法设计思路简单,仿真结果表明该方法有较好的控制效果,能满足布撒器BTT控制的要求。As far as bank to turn missile is concerned, it is imperative to make sideslip angle as small as possible. And this also is a critical issue for BTT steering pilot to restrict sideslip angle resulting from rapid roll maneuvers. In this paper, H_∞ controllers with high robustness are designed for pich, yaw and roll channel respectively using decoupled linear time invariant model. Model parametric variations from aerodynamic coefficient uncertainty are taken into consideration. Then a coordinated branch is introduced into the yaw channel in order to limit the sideslip angle. Simulation results show that this method makes coordinated BTT autopilot design easier,and can get a good result that meets the requirements of BTT control.
