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 ,并提出了仿真算例 The seismic signal is decomposed into the deterministic part of the bounded set description and the indefinite part of the digital characterization of the random variable. Based on the norm analysis of the seismic signal and the structural system, the hybrid control optimization index J is used as the optimization target, Out of its physical meaning. Aiming at the advantages and disadvantages of H2 control scheme and H∞ control scheme, a H2 H∞ hybrid control scheme of minimizing the index J given the γ value is given, and a simulation example
