摘　　要：本文提出了瞬时开闭环最优控制算法，这是建立在时程分析基础上的最优控制算法，不需要实施结构的模态解耦，适合于地震动作用下非线性结构的控制分析。这种算法不仅可以区分开环、闭环和开闭环控制的不同效果，而且结构的位移、速度和加速度响应都能有效地得到控制。his paper puts forward the instantaneous optimal open-close-loop control algorithm.It is an optimal control algorithm based on time history analysis method.Needless to decouple the structure modes,it is quite suitable for control analysis for nonlinear structures under earthquake excitations.The new algorithm has a distinct physical meaning,which means different control effects of the open-loop,closed-loop and open-closed-loop control.Moreover,the displacement,velocity and acceleration response can be efficiently controlled simultaneously.
