“…shells with classical and non-classical boundary conditions [22][23][24][25][26][27]. Ma et al [28] investigated the active control of an elastic cylindrical shell coupled to a vibration isolation system. The cylindrical shell is simply supported at its two ends and four active control strategies are evaluated in terms of the acoustic power radiated from the supporting shell.…”

This paper aims to address the intelligent active vibration control problem of a flexible rectangular plate vibration involving parameter variation and external disturbance. An adaptive sliding mode (ASM) MIMO control strategy and smart piezoelectric materials are proposed as a solution, where the controller design can deal with problems of an external disturbance and parametric uncertainty in system. Compared with the current 'classical' control design, the proposed ASM MIMO control strategy design has two advantages. First, unlike existing classical control algorithms, where only low intelligence of the vibration control system is achieved, this paper shows that high intelligent of the vibration control system can be realized by the ASM MIMO control strategy and smart piezoelectric materials. Second, the system performance is improved due to two additional terms obtained in the active vibration control system. Detailed design principle and rigorous stability analysis are provided. Finally, experiments and simulations were used to verify the effectiveness of the proposed strategy using a hardware prototype based on NI instruments, a MATLAB/SIMULINK platform, and smart piezoelectric materials.

“…A fe/be coupling for control of noise radiation and sound transition is considered in Larbi et al by introducing a passive control on an elastic structure coupled to external/internal acoustic domains. Active control simulation is considered by Ma et al in for an elastic cylindrical shell coupled with a fluid. They also consider the effect of the supporting structures in the sound radiations.…”

Summary In this paper, we propose a numerical method based on an active structural control to dampen the discrete critical frequencies from a fe/be coupled system, which models a time‐harmonic fluid‐structure interaction problem. The active structural acoustic control used consists of applying external forces directly on the structure, so that in the presence of critical frequencies, the linear system remains stable and, in turn, in the presence of non‐critical frequencies, the active control does not alter the system. We consider the problem in the framework of the theory of optimal control and present bi‐dimensional numerical simulations to show the behavior of the scheme in some vibro‐acoustic structures.
