基于模糊Smith控制的时滞系统设计与仿真 ??????摘要??????今天的工业生产在面对日益复杂的控制问题伴随着科技的进步状态,时间延迟,但是,很难避免工业控制 HYPERLINK javascript:; 的内在特征, 它不仅降低了系统的稳定性,也严重影响工业生产过程的质量控制,模糊控制作为一种基于模型参数的控制方法的研究成为了一个热点。MATLAB在本文中结合了模糊控制和Smith控制，即模糊—Smith控制,不仅补偿滞后的缺点,也较强的适应控制对象的参数变化,具有一定的实际应用前景。 HYPERLINK javascript:; 大时滞工业生产过程中经常运用于冶金、炼油、化工、电力、航空航天和经济管理中，还在大时滞工业过程估计控制系统以传统的史密斯为主, Smith预测控制是延时控制最有效的控制方法,它不仅克服控制系统中的各类缺陷,也可以使模糊控制和Smith预估器相结合,对于模糊控制应用于纯时滞系统在某种程度上是更成功的。??????关键词：模糊控制; Smith控制; 时滞系统; MATLAB。?????????????Based on the fuzzy - Smith control design and simulation of time-delay systems????????????Abstract??????In todays industrial production in the face of increasingly complex control problems along with the progress of science and technology condition, time delay, but it is hard to avoid the inherent characteristics of the industrial control, it not only reduces the systems stability and serious influence the industrial process control s quality , fuzzy control, as a kind of control method based on model parameters become a hot spot of research. MATLAB in this paper combines fuzzy control and control become blurred - Smith. Smith control, not only compensate the disadvantage of lag, and to adapt to changes in the parameters of the controlled object, has a certain practical application prospect. Large time delay is often used in the process of industrial chemical, oil refining, metallurgy, electric power, aerospace, economic management and traffic system. Also in large industrial processes with time-delay estimation control system is given priority to with the traditional Smith, Smith predictive control is the most classical and most mature time delay control method, it not only make the set value input zero steady-state error and external disturbance, also can be combined with fuzzy control and Smith estimates????????????Key words: Fuzzy Control; Matlab; Delays; Smith control??????目 录??????摘 要 Ⅰ??????Abstract Ⅱ??????目 录 Ⅲ??????1引 言 1??????1.1选题的背景及意义 1??????2绪论 2??????2.1 研究的内容及方法 2????
