柔性建筑结构风振自适应控制方法与试验研究

对基于惯性质量型作动器与自适应滤波技术的前馈控制方法用于柔性建筑结构风振控制进行了研究，涉及建模、控制律设计、数字仿真直至风洞模型试验等各个方面。针对柔性建筑结构风振控制的特点，设计与制造了主动式惯性质量型作动器，提出取与受控对象第一阶模态频率同频的正弦信号为自适应控制器的参考输入，建立了一套由ＰＣ机、ＴＭＳ３２０Ｃ３０高速数字信号处理器与多路Ａ／Ｄ，Ｄ／Ａ组成自适应振动控制系统，并进行了计算机仿真与风洞试验。计算机仿真与风洞试验所获得的良好减振效果验证了所提出的控制方法的正确性。

Adaptive Control of Wind Induced Vibration of Flexible Civil Structures:Methods and Experiments

The paper deals with active control of wind induced vibration of flexible civil structures based on proof mass actuators and adaptive filter. It covers the modeling, controller design, digital simulation, actuator manufacture and wind tunnel test. Three kinds of reference signals are considered, i.e. dynamic wind presssure, reconstructed response induced by disturbance, and the sinusoid with the frequency of the first modal frequency of the controlled structure. The simulation shows that the vibration reduction for the third reference signal is similar to that for the first reference signal. An adaptive control system is also built up, which consists of a PC, the TMS320C30 DSP board, multichannel A/D, D/A convertors, the made by ourselves proof mass actuator, etc. The evident vibration reduction is observed in both the digital simulation and the wind tunnel test.
