摘　　要：针对土木工程中系统全响应状态难以直接获得的问题,结合状态观测理论,提出以加速度作为反馈状态的自适应控制算法,并在AMD-钢框架实验系统中进行了实验分析。根据实验结果,在地震波激励作用下,所提出的基于加速度的MCS控制算法具有良好的减振控制效果。The minimum control synthesis(MCS)algorithm do nott depend on structural mathematical model and parameters,which has good adaptability for nonlinear systems and is very suitable for vibration control of civil engineering structures.To solve the problem that the full response state of the system of civil engineering structures is hard to directly obtain,combined with the state observation theory,an adaptive control algorithm with acceleration being the feedback state was proposed,and the experimental analysis was conducted in the AMD-steel frame system.According to the experimental results,under the action of seismic wave excitation,the constructed MCS control algorithm based on acceleration feedback has excellent damping control effect.
