摘　　要：建筑物迁移所采用的工程装备是电液比例控制的多驱动单元系统,并且由于建筑物迁移过程中工况复杂,存在各种不确定因素。据此,本文采用H∞控制策略,设计了同时抑制干扰和受控对象不确定性的H∞混合灵敏度控制器。通过对系统加入H∞控制器与LQG(线性二次高斯)控制器的阶跃、脉动、方波响应进行对比,结果证明H∞控制理论在建筑物迁移控制的应用,能够更好地实现跟踪,使建筑物迁移更加安全、平稳。Equipment used in structure moving is electro - hydraulic proportional control muti - drive unit system, and because of the complexities of operation, there are many uncertainties during the course of structure moving. H∞ control theory was employed to solve the problem of restraining disturb and uncertainty of controlled object simultaneously. Compared with impulse, step, square wave response of the two systems with H∞ controller and LQG controller, the result shows that good track and moving calmly are realized by applying H∞ control theory to equipment control system for structure moving,
