本文研究了用智能传感器构成的滤波器对柔性梁进行主动波控制。本文提出了一种新颖的PVDF膜传感器滤波方法及其在自适应前馈控制系统中的应用。首先，介绍了采用异形PVDF传感器的滤波器的设计过程。在引入PVDF传感器时，将整形函数定义为复函数。在这种情况下，乘一个虚单位相当于使相位差为90度。其次，从数值分析的角度，阐明了波滤波器的精度和控制系统的性能。最后，对有源波前馈控制系统进行了实验，验证了所提方法的有效性。
This paper deals with active wave control of a flexible beam using a wave filter constructed with smart sensors. It is the purpose of this paper to present a novel wave filtering method using PVDF film sensor and its application for adaptive feedforward control system. Firstly, the design procedure of the wave filter using shaped PVDF sensors is presented. When introducing PVDF sensor, shaping function is defined as a complex function. In this case, multiplying an imaginary unit is equivalent to making the phase difference of 90 degree. Next, from a viewpoint of numerical analysis, the accuracy of the wave filter and the performance of the control system is clarified. Finally, an experiment of the active wave feedforward control system is carried out, demonstrating the validity of the proposed method.
