对大机动弹头再入飞行段姿态稳定控制系统的设计问题进行了分析与研究。根据飞行控制要求 ,考虑了影响较大的气动力和气动力矩因素 ,建立了一个完全表征大机动情况下弹头运动的非线性动力学模型。然后采用非线性解耦控制理论设计了机动弹头的姿态控制系统。仿真结果表明 ,该方法能够保证系统良好的稳定性能。
The design of the attitude stability control system for the large maneuverable warhead reentry flight segment is analyzed and studied. According to the requirements of flight control, considering the aerodynamic and aerodynamic factors that have great influence, a nonlinear dynamic model is established to fully characterize the warhead movement under large maneuvering conditions. Then the nonlinear decoupling control theory is used to design the attitude control system of the mobile warhead. Simulation results show that this method can ensure good stability of the system.
