摘要
针对一类bang-bang类型连续微分对策制导律,研究了在离散信息模式下的数字执行方法.基于对线性系统和终端脱靶量性能指标的推导,提出一种bang-bang制导律常值最优离散化执行方法,可实现对于传统最优采样保持离散化方法的最好近似,同时可以避免抖振,更易于执行.针对3种连续时间微分对策制导律DGL/0,DGL/1和DGL/C进行了仿真.该方法也很容易扩展到其他bang-bang类型控制律的研究领域.
The digital implementation method was researched for a class of bang-bang control continuous differential game guidance law(DGL).Based on the derivation of linear system and terminal miss distance performance index,a constant optimal digital implementation method was presented for bang-bang guidance law.This method can realize the best approximation of sample and hold method and can avoid chatting of control command,so it was easy to implement.And it was applied to the simulations of three continuous differential game guidance laws:DGL/0,DGL/1 and DGL/C.This method was also easy to be extended to other research fields with bang-bang control.
