中文摘要：

作为盘子由作者更早开发了的压电的横梁类型的颤动控制的小浪途径的延期，这份报纸建议为压制把压成薄片的矩形的盘子的颤动的混合 activepassive 控制策略经由薄粘弹性的结合层与分布式的压电的传感器和致动器结合了。由于在直角的小浪理论放大函数变换的低通行证的过滤性质，这个 waveletbased 控制方法有能力自动地在反馈控制循环滤出像噪音的信号，因此减少剩余联合的风险完成哪个通常是溢出的来源不稳定性。而且，薄粘弹性的结合层的存在能进一步通过浪费数字错误在控制过程期间部分导致的任何另外的可能的噪音的体力改进系统的坚韧性和可靠性。一个模拟过程基于一种先进 wavelet-Galerkin 技术被建议认识到混合活跃被动的控制进程。数字结果表明建议途径的效率。

英文摘要：

As an extension of the wavelet approach to vi- bration control of piezoelectric beam-type plates developed earlier by the authors, this paper proposes a hybrid active- passive control strategy for suppressing vibrations of lami- nated rectangular plates bonded with distributed piezoelec- tric sensors and actuators via thin viscoelastic bonding lay- ers. Owing to the low-pass filtering property of scaling func- tion transform in orthogonal wavelet theory, this wavelet- based control method has the ability to automatically filter out noise-like signal in the feedback control loop, hence re- ducing the risk of residual coupling effects which are usu- ally the source of spillover instability. Moreover, the exis- tence of thin viscoelastic bonding layers can further improve robustness and reliability of the system through dissipating the energy of any other possible noise induced partially by numerical errors during the control process. A simulation procedure based on an advanced wavelet-Galerkin technique is suggested to realize the hybrid active-passive control pro- cess. Numerical results demonstrate the efficiency of the pro- posed approach.
