摘要:
考虑运载火箭飞行过程中的弹性振动特性,对运载火箭进行全量动力学建模以及控制器设计。首先将运载火箭考虑为一维梁模型并建立全量动力学模型,分别引入自适应滤波姿态控制算法和H2范数鲁棒增益调度控制算法设计控制器。仿真结果表明:在考虑舵机非线性情况下两种控制方法均能够满足精度要求,在具有较大外部扰动情况下,鲁棒增益调度控制算法相较于自适应滤波算法具有较强的鲁棒性。

Abstract:
Modeling and controller designing for rocket launcher was carried out considering its elastic characteristic during the flight Firstly a full variable dynamic model for the launcher was established based on the one dimensional beam, An adaptive filtering attitude controller and a H2norm robust gain-scheduled controller were introduced Simulation results show that the both controllers perform well without neglecting actuators’ nonlinear characteristic, and the latter is of more robustness against large outer disturbance
Key words:  Elastic vibration  Full variable dynamic model  Rigid-elastic coupling  Adaptive filtering  H2norm Robust gain-scheduled control
