摘要
本文针对采样控制系统连续信号与离散信号共存的特点,指出传统离散化分析方法因忽略了系统在采样时刻之间的信息导致无法精确、真实地反映采样控制系统的时间响应特性,在此基础上,应用采样控制系统直接设计方法,基于提升技术,在考虑系统在采样时刻之间全部信息的条件下,推导给出了采样控制系统时间响应的计算方法,最后通过一个具体计算实例说明了本文方法的有效性。
In this paper, we firstly aimed at the coexist characteristics of continuous and discrete signals in a sampled-data control system, and pointed out that the traditional time response computation for such systems is inaccurate and untrue because of ignoring the information between the sampled interval. Secondly, applying the direct design method of sampled-data systems, basing the lifting technology ard considering all the information between the sample interval,we derived and gave a time response computation method. Finally, we provide a concrete computation example to illustrate the -validity of the method in this paper.
