【Abstract】 In this paper, a semiactive control system is proposed and its control theory is analyzed. Predictive control which combines modern control theory, is applied to the semiactive control system of structurel in earthquake engineering. The algorithm of online predictive control is developed. The model of predictive control is set up ,and a method that solves timedelay 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 semiactive 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.更多还原
