压电致动器和传感器越来越多地用于涉及振动/位置/形状控制装置的应用中。基于传感器和执行器无缝配置的自感知执行器（SSA）概念，研究了固支板的鲁棒控制问题。建立了表面粘贴压电片板的解析模型，设计了μ综合控制器，以抑制受扰动的固支板的多模态振动。实验结果表明，采用对称和非对称布置的两个压电片的反馈控制，可以有效地抑制对称和非对称模态。
Piezoelectric actuators and sensors are increasingly being used in applications involving vibration/position/shape control devices. Based on the self-sensing actuator (SSA) concept in which the sensors and actuators are seamlessly collocated, this paper presents a study on the robust control of a clamped plate. An analytical model of a plate with surface-bonded piezoelectric patches is derived and a μ-synthesis controller is designed to suppress multi-mode vibrations of the clamped plate under perturbations. The experimental results show that the symmetrical and asymmetrical modes can be effectively suppressed with designed feedback control using two piezoelectric patches which are positioned symmetrically and asymmetrically on the plate, respectively.
