摘　　要：针对一阶加纯滞后模型 (FOPDT)及二阶加纯滞后模型 (SOPDT) ,本文介绍了基于模型估计的内模控制 (IMC)、外模补偿控制 (EMC)、Smith预估控制这三种对克服对象纯滞后实用有效的控制方法。且对各类控制器提供了详细的设计方案 ,其特点是结构简单易于实现。For process with time delay this paper mainly presents external model controller(EMC),Internal model controller (IMC) and Smith predictor which are all based on model estimation.Details are provided about how to design the controllers separately for a first order lag process with dead time (FOPDT) and a second order lag process with dead time (DOPDT).Simulation results are given to show the methods more clearly.
