基于观测模型的基准建筑物的振动主动控制方法

将观测参考模型的控制方法应用于振动主动控制，提出了一种新的控制策略。首先，考虑到主动控制目的是减弱系统的动力反应，在设计跟踪模型时，采用小幅值的处理方式；其次，考虑到主动控制时的外激励是随机的，在控制增益确定方面，提出了删除与跟踪相关的项；再次，为保持各作动器均衡出力，提出了权矩阵的概念。最后，给出了一个３层基准建筑物的仿真实例，结果表明提出新的控制策略是可行的。

Approach for Active Vibration Control of Benchmark Buildings Based on Observation Model

The control approach for observation-based model is applied to active vibration control, and a new control strategy is proposed. Firstly, considering the purpose of active control is to weaken the dynamic responses of the system, a small-amplitude-processing method is used when designing the tracking model. Secondly, as the external excitation in active control is random, the item concerned with tracking is proposed to be deleted when designing the control gain. A- gain, the concept of weight matrix is suggested to keep the balanced output of each actuator. At last, a 3-storey bench- mark structure is presented, and the simulation results show that the new control strategy proposed here is viable.
