本文指出了文献[1]存在的问题,给出了非零初始状态下网络响应的卷积积分公式的正确描述。 文献[1]利用块-脉冲函数(或称方波脉冲函数),根据卷积积分和卷积积分的时域分段方法讨论了线性定常的开环与闭环系统。 文献[1]在提要中明确指出,这些系统的初始状态可认为是非零的。并对该文图1开环系统的输入-输出关系,用(7)式 This paper points out the problems in [1], and gives the correct description of the convolution integral formula of network response in non-zero initial state. In [1], the block-and-pulse function (or square wave pulse function) is used to discuss the open-loop and closed-loop systems with time-delay based on the convolution integral and convolution integral. The literature [1] clearly states in the abstract that the initial state of these systems can be considered non-zero. And the open-loop system of Figure 1, the input-output relationship, using (7) type
