倾斜转弯导弹三回路鲁棒自动驾驶仪设计

Three-loop robust autopilot design for bank-to-turn missiles

针对倾斜转弯导弹,提出了最优/经典综合设计方法设计自动驾驶仪。该方法应用最优控制设计出俯仰/偏航混合通道三回路自动驾驶仪,设计中同时对开环系统的奇异值频域曲线进行约束,以保证系统具有一定的鲁棒性,获得的三回路自动驾驶仪结构简单,易于工程实现。仿真结果证实了其具有良好的跟踪性能和鲁棒性,也表明该自动驾驶仪能满足倾斜转弯导弹协调倾斜转弯的要求。

For bank-to-turn missiles, a combined optimal/classical approach is brought out to design the autopilot. A three-loop autopilot of the pitch/yaw mix channel is designed using optimal control; meanwhile the singular value of the open-loop system is tested in frequency domain, to have the robustness of the system insured, and the obtained three-loop autopilot has the characteristic of simple structure, so it is more practical. Finally, the simulation results demonstrate the tracking performance and robustness of the autopilot, and also show that it satisfies the requirements for coordinate bank-to-turn.
