摘要
针对固体导弹(火箭)主动段姿态控制系统,采用解析方式分别建立了控制参数与幅值裕度和相位裕度之间的映射关系。该映射关系不依赖于模型参数,在该映射关系的基础上,可以快速得到与期望的稳定裕度变化量对应的控制参数的变化规律,即可用于实现稳定裕度的在线调节。仿真结果表明,利用该映射关系较好地实现了稳定裕度的在线调节。
Aiming at attitude control problems of solid missile( launch vehicle) boost-phase,analytic mapping relationships among control parameters and amplitude margin or phase angle margin are proposed separately,by which the regulating rules of control parameters in accordance with the expected stability margin can be obtained rapidly without model information. Simulation results demonstrate that stability margin can be adjusted online effectively in terms of the proposed mapping relationships.
