两种结构预测控制律的研究

ON TWO STRUCTURE FORECASTING CONTROL RULES

为了解决结构控制计算复杂及控制力迟时等问题,用GM(2,1)模型模拟了地震作用,深入研究了控制力的预测和迟时控制方法。采用模糊控制和次优控制方法研究了受控结构的减震效果。研究表明,两种控制方法均能有效地减小结构的地震反应,通过合理选取控制系统的参数,次优控制方法能取得接近模糊控制的控制效果。

In order to avoid the complicated calculation and solve the time-delaying problem of structure control, the earthquake action is simulated with GM (2,1) model in this paper. The control force forecasting and time-delay method are discussed in detail. The control effects of structure under earthquake excitation are studied by using the fuzzy control method and the second optimization control method. Results indicates that both control methods achieve excellent effects and the second optimization control method can behave as well as fuzzy control method after optimizing its control parameters.
