摘要
本文研究应用可变阻尼器对线性结构进行半主动控制的算法和原理。采用滑动模态控制算法,并基于Lyapunov直接法提出了半主动控制器设计。利用滑动模态控制方法和所建立的控制器,我们给出了一个风荷载激励下的线性结构的半主动控制算例。计算机模拟分析表明,半主动控制具有控制效果明显、鲁棒性好等优点,是一种非常有发展前途的控制方法。
おn this paper,the algorithms of semiactive control for applications to seismically excited or wind induced linear structure are studied.The control methods are based on the theory of variable structure system (VSS) or sliding mode control (SMC).A new kind of controller is proposed based on the Lyapunov direct method.Using the SMC method and the controller proposed,an numerical example is given.Simulation results demonstrate that the control methods presented are effective.
