中文摘要: 本文讨论了三种用于纯滞后过程的观测补偿器控制方案。第一种方案与Smith预估补偿方案进行了比较,表明它具有实施方便、对于对象模型参数的变化不灵敏以及稳定性较好等优点。第二种方案与前馈控制相类似,通过合适的观测补偿器参数的选择,可以完全补偿可测干扰的影响。第三种方案综合了前两种方案的优点,它不仅有良好的稳定性,而且有较强的适应能力。数字仿真的结果表明这类观测补偿器控制方案还可适用于对象是时变或者非线性的系统。
Abstract:This paper is concerned with the disscussion of observer compensator control schemes of the process with time delay. The first control scheme discussed has the following advantages over that based on the Smith predictor: easy to install and robust for the changing of process model parameters. The second one, analogous to feedforward control, has the capability of fully overcoming the effect due to measurable disturbances. The last control scheme presented in this paper, having the advantages of the previous two schemes, is characterized by good stability and adaptive nature and digital simulation studies show that it can also be applied to time-variant and nonlinear processes.
