结构主动控制的一种瞬时最优算法

An instantaneous optimal algorithm for structural active control

非线性结构时程分析的高阶单步算法是一种新的求解运动方程的直接积分法。该方法无条件稳定，无超越现象，具有三阶以上精度。本文将高阶单步算法用于结构的瞬时最优主动控制。由于该方法比Ｎｅｗ．ｍａｒｋ－β法，Ｗｉｌｌｓｏｎ－θ法等具有高得多的精度，因此，获得了比其它瞬时最优算法更显著的控制效果。

The high order single step algorithm is a new method of direct integration for solution equations of motion The method is unconditionally,on overshooting and has more 3 steps considera- tion In this paper ,the high order single step algorithm was applied to instantaneous optimal active control of structures The computer simulation results demonstrate that control effective is better than Newmark-β and Wilson-θ method because the algorithm has 4 steps precision and higher speed
