| 摘 要： | 提出了一种以动量轮为执行机构的具有中性静稳定气动布局的再入弹头姿态控制新方案。基于动量矩交换原理和中性静稳定概念分析了新方案的可行性,并推导了具有这种新型执行机构的弹头的姿态动力学方程。利用反馈线性化方法,将姿态动力学方程线性化并解耦成俯仰、偏航和滚转三个方向上的单输入单输出系统,然后运用滑模变构控制理论设计各通道的控制器。对姿态控制系统的数值仿真结果表明,所设设计的控制器能实现高精度的姿态机动和姿态稳定,现有动量轮技术指标即可满足滚动通道的姿态稳定。

| Abstract: | A novel set of moment wheel actuators is proposed to control a reentry warhead with indifferently static stability.This design is theoretically analyzed by the momentum theorem and the indifferently static stability conception.The attitude dynamic equation of the new actuator warhead is derived.By the method of feedback linearization,the attitude control system is linearized and decoupled into three SISO linear systems in pitch,yaw and roll channel respectively.The attitude controller of each channel was designed base on the sliding mode variablestructure control theory.Numerical simulations of the attitude control system indicated that the controller is capable of controlling the attitude maneuver and stability and warhead is small. |
