摘要
在拦截高速高机动目标时,针对目标作随机机动,估计、制导系统独立设计的前提条件-分离定理和确定性等价原则不再满足,也不存在一个全局的估计/制导算法对所有的目标机动方式均为最优的问题,讨论了它估计/制导系统综合设计的必要性。并考虑到制导/控制综合设计的系统比独立设计的制导、控制系统有更优越的性能,以及高阶滑模控制有优良的控制性能,给出了一种基于高阶滑模的多模估计/制导/控制综合设计系统的结构。
When intercepts the high velocity and highly maneuverable target, for the maneuver of the target is random, the principle of separation and certainty equivalence are not validity during the design estimator and guidance system of intercepting missile, there is no global optimal estimate/guidance law for all feasi- ble target maneuver, therefore, the necessity of integrated design of estimate/guidance system are discussed. Considering guidance/control integrated design system is advantage than the one which separate designed, and higher-order sliding mode control has good performance, a higher-order sliding mode control based multi-model estimator/guidance/control integrated design system structure for interceptor missile is presented.
