摘要
本文在只能获得加速度时 ,通过改变 Leunberger观测器的结构形式 ,基于模态滤波器技术、最优控制理论和计算机控制系统理论 ,采用独立模态空间控制策略进行了具有密集模态的空间柔性智能桁架结构的实时计算机振动主动控制实验研究。实验结果表明这种控制策略是行之有效的。
The study of vibration control of flexible space intelligent truss structures with acceleration measurements is of importance since accelerometers are used widespreadly because of wide frequency range and lightweight.The Leunberger observer is modified to fit to acceleration measurements.Based on Modal Filters(MF) and the optimal control theory,an Independent Modal Space Control(IMSC) method for space intelligent truss structures with closely spaced frequencies via acceleration measurements is developed.Real time computer active vibration control experiments demonstrate that the control strategy is effective and feasible.
