摘　　要：介绍了一种基于内模设计的Smith预测控制器的设计方法.该方法通过继电反馈实验获取过程对象的模型参数,并融入了自适应的控制思想,能较好地解决模型失配问题.实验结果表明,该控制器算法简单,容易实现,对延时较大的系统有很好的控制效果.This paper presents a new method on designing Smith predictor based on the internal model control(IMC) theory. This method is capable in solving the mismatch problem by identifying the model parameters of process objectives through relay-based feedback and adopting the self-adaptive theory. The experimental result indicates that this simple and easily utilized algorithm can achieve outstanding results in the control systems with large time-delay.
