    摘要:

    传统制导律多基于常速运动假设, 与实际情形并不一致, 往往无法提供满意的性能. 对此, 基于微分对策理论, 提出一种适用于变速拦截情形的有界控制非线性制导律. 将对策双方的速度变化直接考虑到非线性相对运动关系中, 并通过适当选取的状态变量进行线性化, 从而设计制导律, 同时考虑可执行性, 并将其转化为原系统非线性状态变量的表达形式. 仿真结果表明, 该制导律可实现目标的有效拦截, 对拦截导弹机动性能要求不高且便于执行.

    Abstract:

    To deal with multiple attributes group decision making problems with linguistic assessment information, a two-
    tuple linguistic multiple attributes group decision making method based on VIKOR method is proposed. This method aggregates single users’ decision information to get group’s decision information, and obtain the best compromise solution by maximizing group utility for the majority and minimizing individual regret for the opponent. This method is easy to implement and interpret, and can avoid the loss and distortion of assessment information effectively. Moreover, the proposed method can overcome the shortcomings of the ideal solution method, which cannot reflect the relative importance of distances from the alternative to the positive ideal solution and negative ideal solution. Finally, the result of the numerical example shows the effectiveness of the proposed method.
