摘　　要：由于SINS/GPS制导炸弹俯仰偏航要进行大空域的机动飞行,导致了其作为被控对象的状态方程参数变化剧烈,就要求飞控系统具有更强的适应能力和鲁棒性。因此,设计了基于模型参考变结构控制方法的鲁棒自动驾驶仪,具有良好的瞬态性能和抗参数大范围变化能力强等优点。以某型SINS/GPS制导炸弹为例,选取典型的气动恶劣条件,进行了按给定制导指令飞行的六自由度全弹道飞行控制仿真。仿真结果表明,该自动驾驶仪能对制导炸弹实现鲁棒自适应控制,为飞控系统设计提供了重要参考。Huge airspace maneuver of guided bomb with SINS/GPS makes parameters of state-equation varying highly. So stronger adaptative and robust flight control system is required. Therefor a robust autopilot having both good transient performance and strong ability of resisting parameter distortion is designed based on model reference adaptive variable structure control method . Then some representative wicked aerodynamic conditions are choosed , and six-degree trajectory simulations of flight control are carried out for a certain type of guided bomb with SINS/GPS. And simulation results confirm the adaptability and robustness of the autopilot, which in turn provide valuable basis for the design of guided bomb＇s flight control system.
