【摘要】 针对实际工业过程控制中常见的双输入双输出时滞过程,提出基于Smith预估补偿控制的反向解耦控制器设计方法。通过对系统解耦后的对象采用内模控制思想设计Smith预估控制器,并讨论控制系统对象为一阶加纯滞后(FOPDT)模型下其控制器的实现方法和系统鲁棒稳定性分析。结合实际过程中的模型实例,该解耦控制方案使得系统各路输出响应完全解耦并具有较好的标称性能和鲁棒性。仿真实例验证了该方案的有效性和优越性。更多还原

【Abstract】 A design method of inverted decoupling control,based on Smith predictive control,is proposed for TITO time-delay process which is common in industrial application.By analyzing the decoupled model,the Smith predictive controller is developed that adopting the concept of internal model control.According to the research on the control model as FOPDT,the method of developing the controller and analysis of robust stability is completed.The decoupling control scheme not only can absolutely decouple the responses of system outputs but also guarantee the nominal performance and robustness.The simulation outcomes verify the effectiveness and superiority of the proposed method.更多还原
