- Using the cogent validity of backstepping " s solving parametric - strict - feedback nonlinear systems , xinghuo yu and wu yuqiang ( 1998 ) solved the output - tracking problem of a kind of linear time varying system by combining nonlinear damping method and variable structure scheme . in this dissertation , we sufficiently consider the effect of disturbances in the input channel basing on the same model
Xinghuoyu和yuqiangwu （ 1998 ）针对一类线性时变系统的输出跟踪问题，基于back飞tepping设计机制，将带有非线性dallpipg项的设计方法与变结构控制方法相结合，给出了一种新的非线性控制器设计方法 - So this base isolation technique has profound prospects . unfortunately there exist definite difficulties in the calculation because of the nonlinear of the base friction force . now , both the equivalent damping method and the numerical calculatin of the vibration response of the base - isolated buildings are frequently used in the calculation of the seismic response of the base - isolated building . however both of them have certain drawbacks . in this paper , the response of the building with base - isolation system is derived by the method of fourier expansion for the friction force and the earthquake response . at the same time , the sliding vibration character of inertia of a single mass structure and the sliding vibration response of a muti - mass structure are discussed . the stable condition of the sliding base isolation system of a structure is given . in the end , two circes of base fixation and base sliding are analyzed by adopting ansys
本文利用对摩擦力和地震响应进行付氏级数展开的方法导出了基底具有摩擦隔震系统的地震反应。同时，文中从研究单质点结构的滑动振动惯性力入手，进而对多质点结构体系滑动振动反应进行探讨，分别给出了结构滑动隔震的自身稳定条件。最后，本文利用ansys对基础固定和基础滑移隔震两种工况进行了动力模拟仿真分析，进一步证实了基础滑移隔规律。
