基于输出预测的姿控发动机控制律优化设计

 针对带有侧向喷流姿控发动机和尾部气动舵的导弹，建立了系统动力学模型和运动学模型，并对模型进行了分析和简化；考虑到侧向过载输出响应快速性的要求，采用侧向喷流发动机提供姿态控制力矩快速建立过载。基于侧向喷流发动机的工作特点，采用Fliess展式得到侧向过载输出的预测和侧向喷流发动机推力放大因子的估计，并以此为基础，提出了以侧向喷流发动机为执行机构的姿态控制律优化设计方法，实现了对侧向过载的快速跟踪。仿真结果说明了所提出方法的有效性。

Output-prediction-based Optimization Design of Missile Attitude Control by Lateral Jets

A dynamic and kinetic model is constructed for a missile with blended lateral jets and aerodynamic fins,from an analysis of which a simplified model is derived. Since the lateral acceleration has to meet fast response requirements,lateral jets are preferable to aerodynamic fins,both of which can provide attitude control torque,but with different response speeds. In this case,the output is predicted via Fliess functional expansion based on the discrete characteristics of lateral jets,and by the same way the ...
