摘要
建立了半主动控制系统的理论模型,分析了半主动控制机理,并结合现代控制理论,将预测控制应用于结构半主动控制中,提出了在线预测控制算法,建立了预测模型,并成功的解决了时滞问题,最后作了计算机仿真分析,证明该系统有较好的控制效果。将预测控制思想应用于结构半主动控制中,为结构控制注入了新的思路,通过研究及仿真分析也说明了这种思想是可行的并且具有很大的发展前途。
In this paper, a semiactive control system is proposed and its control theory is analyzed. Predictive control which combines modern control theory, is applied to the semiactive control system of structurel in earthquake engineering. The algorithm of online predictive control is developed. The model of predictive control is set up ,and a method that solves timedelay problem based on predictive control is presented . The computed control result has proved fully that the method is correct and practical. In this paper the conception of predictive control is applied to the semiactive control of structure,and a new way of structure control is found. The study and simulation result have shown that this conception is applicability and has a good future.
