时延过程的抽样控制统系

The Sampled Control System Containing Time Delay

本文研究基于Smith原理的时延控制系统在离散域中的特性,提出一种易于用计算机实现的时延过程控制系统模型.它能有效地解决分数时滞带来的问题;适当选择控制器参数,能获得对阶跃参考输入响应和对阶跃干扰响应的理想稳态特性和瞬态特性.本文还给出系统仿真曲线.

This paper is concerned with the property of time-delay system which is based on Smith's principle. A new model of control system containing time delay, which can be easly realized by computer, is proposed. This control system can effectively solve problems caused by fraction delay. Selec.ed proper parameters, the sampled control system can yield desired s■eady and transient responses to s■ep■eference input and step dis urbances. This paper also gives some simulation curves of control system.
