摘要: 研究基于分步变换及设计思想的具有控制滞后的离散时滞系统控制器设计问题.针对一 类控制滞后的离散时滞系统,提出了一种带控制记忆的时滞变换,使得原时滞系统经过分步等 价变换后得到无滞后的线性能控系统,从而利用分步设计的思想实现离散时滞系统控制器设 计的目的,并给出了其稳定性证明.最后以一工业电加热炉被控对象为例,通过仿真说明了 该方法的有效性和可行性.Abstract: In this paper, a control design approach for discrete linear systems with delayed control based on step-by-step design idea is presented. A delay transformation with past control array is applied to transform a time-delayed system into a linear system without delayed control. The controller to the primitive time-delayed system is derived via a step-by-step design method. The simulation result of an example for industrial electric heater shows that this approach is effective.
