简介:传统的控制策略有困难在地震刺激下面处理结构,时间变量特征和构造控制系统的参数不确定性的非线性的行为。与模糊控制相结合的off-and-towards-equilibrium(OTE)策略在这篇论文被介绍克服这些困难。根据OTE策略,控制力量从在结构,令人激动的力量和控制力量的运动之间的一种机械关系的观点被设计。OTE策略的优点是它能被用于许多控制系统。以便评估建议策略的表演,地震表演一三故事砍用一个模糊逻辑控制器(FLC)与一个活跃的腱系统(ATS)造被学习。模糊控制器的主要优点是它处理结构的任何非线性的行为的固有的坚韧性和能力。然而,没有设计指南为FLC建立相应检核尺桌子。为FLC基于建议策略,在学习下面与大楼联系的一张检核尺桌子被开发,它然后允许一个详细算法的形成。在这研究获得的结果证明建议策略比线性二次的管理者(LQR)稍微好表现策略,当在LQR控制器上拥有几个优点时。因而,建议策略的可行性和有效性被验证。
