基于模型参考的SINS/GPS制导炸弹俯仰偏航控制

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SlNS/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.

Pitch Yaw Channels Control based on Model Reference of a Guided Bomb with SINS/GPS

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...
