By investigating the truncated problem, we could prove that the original problem admits a sequence of small solutions.

通过研究截断问题的弱解，我们证明了原问题存在一列非平凡的小解。

The improved algorithms can reduce significantly the truncated error of the truncating unit pulse (or step) response time-sequence of the controlled process as the internal model.

改进算法可有效减小截取被控对象时间响应(单位方波或单位阶跃响应)有限序列为内模的截断误差。
