本文提出了两种连续有限时间收敛控制算法，在匹配和不匹配无界干扰存在的情况下，使用标量输入驱动n维积分器的输出（最高相对度状态）在有限时间内趋近于零。不需要所有系统状态的知识：只有输出应该可用于控制设计。也没有假设个体干扰的知识或重建。本文最后以控制工业基准直流电机为例进行了研究，该电机的三阶数学模型受到匹配和不匹配扰动的干扰。
This paper presents two continuous finite-time convergent control algorithms driving an output (the highest relative degree state) of an n-dimensional integrator to zero for a finite time using a scalar input in the presence of both matched and unmatched unbounded disturbances. No knowledge of all system states is required: only the output should be available for the control design. No knowledge or reconstruction of individual disturbances is assumed as well. This paper concludes with a case study of controlling an industrial benchmark DC motor, whose third-order mathematical model is perturbed by matched and unmatched disturbances.
