常向量 meaning in English

constant vector

By applying new mathematical analysis techniques , an equal discrete system of delay difference equations is introduced , some asymptotic behavior of solutions for this system is obtained , which can be used to get some new sufficient conditions to ensure that every bounded solution of such a delay difference equations converges to a constant vector
摘要利用新的数学分析技巧，引入了与时滞差分系统等价的离散动力系统，建立了离散系统的若干收敛性质，提出时滞差分系统的每个有界解渐近到常向量的充分条件。
The nonrecursive algorithm is proved to terminate in finite steps and turn out to be a constant vector too . because two modifications estimated models are asymptotically uniformly nonsingular , thus the possible singularity in the adaptive pole placement systems is completely avoided . however the prior knowledge required is only the observability indices of systems , thus , the required prior knowledge is greatly reduced
非迭代的修正策略证明了参数修正向量在有限步内收敛于一个常向量；上述两种修正策略均保证了估计模型的一致能控性，从而彻底解决了自适应极点配中可能出现的奇异性问题，而所需的先验知识仅为系统的能观性指数。
