摘要
将地震信号分解为有界集合描述的确定性部分和随机变量数字特征描述的不确定部分 ,在地震信号和结构系统的范数分析基础上 ,使用了混合控制优化指标J作为优化目标 ,并给出其物理含义。针对H2 控制方案和H∞ 控制方案的优缺点 ,给出了在给定γ值的前提下极小化指标J的H2 H∞ 混合控制方案 。
An earthquake signal is divided into a definite part described by a limited aggregate and an indefinite part descibed by stochastic variables.Based on the norm analysis of the earthquake signals and the structural system,the mixed optimal control index J is used as the object of optimization,and its physical implication is also defined.In connection of the merits and demerits of the control scheme H 2 and H ∞,mixed control schemes that minimized the index J with γ as a given definite value are presented.An example imitating real project is given.
