摘要
本文分析了文献[5]中方法的不足,提出了梁式结构振动主动控制中同时优化系统极点和传感器/作动器位置的联合优化设计法,指出传感器/作动器最优位置不仅与受控结构的模态频率和振型有关,还与系统的极点位置有关.对于最低阶模态频率较低(小于1.0 rad/s)的受控结构的主动控制系统不宜采用加速度传感器.
In the paper, the disadvantages of the method formulated in Ref. [5] are analysed. Based on the analysis, a unified optimum design method used to determine the optimal system poles and sensors/actuators locations is presented.Then, it is pointed out that the optimal placements of sensors/actuators are relative to not only the mode frequencies and shapes of controlled structure, but also the system poles. Accelerators are not suitable for controlled structures with lowest mode frequency less than 1.0 rad/s.
