Some notes are presented on the paper “Finite-Time Control of Uncertain Fractional-Order Positive Impulsive Switched Systems with Mode-Dependent Average Dwell Time ” by Liu L. et al (Circuit Syst Signal Processing 37: 3739–3755, 2018). Fractional calculus has the memory property and this is relevant to the whole process from the initial value \(t_{0}\) to the current time t. However, this important property is neglected in the above paper, and consequently, the main outcome is incorrect. A counter example is presented to verify our analysis.

关于“不确定的分数阶正脉冲切换系统具有模式相关平均停留时间的有限时间控制”的评论

Liu L.等人（电路系统信号处理37：3739–3755，2018年）在论文“不确定的分数阶正脉冲切换系统的有限时间控制与模式相关的平均停留时间”上作了一些说明。小数演算具有存储属性，这与从初始值\（t_ {0} \）到当前时间t的整个过程有关。但是，以上论文忽略了这一重要属性，因此，主要结果是错误的。提出了一个反例来验证我们的分析。
