针对重复使用亚轨道飞行器无动力自动着陆的横侧向控制,偏航通道根据状态反馈和输出反馈理论将“偏航角速度+偏航角”反馈转换成适于工程应用的“偏航角速度+侧向过载”控制方式;滚转通道设计了“滚转角速度+滚转角”控制方式,在此基础上首次推导了BTT控制方式侧偏距回路的稳定性分析原理,并据此理论设计了横侧向回路的控制参数。仿真结果表明所设计的横侧向控制器能够快速消除侧滑角,有效消除侧偏距,并且对平稳风和切变风有较强的鲁棒性。 For lateral lateral control of reusable sub-orbital aircraft without power automatic landing, the yaw channel converts the “yaw rate + yaw angle” feedback into “yaw” for the engineering application according to the state feedback and output feedback theory Angular velocity + lateral overload “control mode; the design of” roll angle speed + roll angle "control mode of roll-off path, and based on this, the principle of stability analysis of side-offset loop of BTT control mode is deduced for the first time and according to This theory has been designed lateral control parameters of the circuit. The simulation results show that the designed lateral controller can quickly eliminate the side slip angle, eliminate the side offset effectively and have strong robustness to steady wind and shear wind.
