| 摘 要： | 加速度传感器具有频带宽、结构简单、重量轻等优点而获得了广泛使用，因此研究基于加速度测量的结构控制系统具有较大的实用价值。文中的只能获得加速度时，采用模态滤波器技术实现从物理加速度响应解耦得到单模态加速度的响应。然后改变Ｌｕｅｎｂｅｒｇｅｒ观测器的结构形式，从模态加速度响应观测得到模态们移和模态速度响应。基于模态滤波器和最优控制理论，采用独立模态空间控制策略，实现了具有密集模态的三维柔性智能桁架结构

| Abstract: | The study of active vibration control of flexible space intelligent truss structures with acceleration measurements is of importance since accelerometers are widespreadly used because of their wide frequency band and light weight. The modal filter (MF) technique is employed to decouple modal response from acceleration measurements. Then modal velocity response and modal displacement response can be estimated from the decoupled modal acceleration. Based on MF and optimal control theory, an independent modal space control (IMSC) method for active vibration control of space intelligent truss structures with closely spaced frequencies via acceleration measurements is developed. Real time simulations demonstrate that the control strategy is effective and feasible. |
