【摘要】 预测控制的理论和应用发展很快，它的三个基本特征预测模型、滚动优化和反馈校正使得它满足了工业实际的要求。 本文以半主动控制为基本控制策略研究了预测控制在结构振动控制中的应用。介绍了目前预测控制和结构振动控制的发展和现状，同时分析了模型算法控制的基本理论优势。通过对建筑结构的分析研究建立了预测模型，结合内模控制的理论设计了半主动控制系统的控制器、并分析了系统的稳定性。最后对一个三层结构的半主动控制系统进行了仿真，从而分析了参数对系统性能的影响，并确定了参数选择的原则。由各种情况的闭环输出曲线和控制量变化曲线分析比较可知，模型算法控制应用与半主动控制系统有着良好的控制性能。这种基于模型算法控制的半主动控制一旦得到广泛应用，可大大提高对结构控制振动的效果。更多还原

【Abstract】 The Predictive Control strategy has been developing quickly both in the theory research and application with its three characteristics of predictive model, receding horizon control construction and feedback correction meeting the industrial process control’s needs.In this paper, we study application of Predictive Control Algorithm in Structure Vibration Control. After introducing the research and development of Predictive Control and Structure Vibration Control, We analyze the basic theory and prepotency of Model Algorithm Control (MAC) . We create Predictive Model by analyzing system of Semi-Active Control. We design the controller of Semi-Active Control system, research stability of system with Internal Model Control (IMC) theory. At last, take a three stories building for example, we select all kinds of parameters and analyze the effect of these parameters. Many simulation curves are given after analyzing those curves we can draw a conclusion that Model Algorithm Control algorithm can improve the control property of system greatly. It is a good algorithm, once the method of Semi-Active Control based on MAC is applied in building, control quality will be enhanced enormously.更多还原
