摘要:
提出极点偏置PDL准则对振动控制中压电传感/驱动器的位置进行评估. PDL准则综合了各阶模态所对应的极点向左偏离虚轴的距离,不仅考虑了各阶模态的阻尼比,确切表达了减振效果,同时判定了稳定性. 数值分析表明,PDL准则能反映压电元件的位置、数量和尺寸,以及反馈增益、模态截取等一系列因素对主动控制的影响,是较为理想的评估压电元件位置的方法.
Abstract:
The Pole Deviated Location criteria (PDL) is presented to assess the placement of piezo-sensor/actuator in vibration control. The PDL Criteria sums up the distance from imagine axle of each mode, which not only express damping effect more precisely, but also can judge structural stability. Numerical simulations show that the PDL criteria can reflect the influence of such factors on active control as the position, quantity, size, feedback gain and truncated modes concerned directly with observability and controllability. It is an effective evaluated basis of position of piezo-sensor/actuator in closed-loop control. 
