Piezoelectric actuator optimization for simultaneous aircraft cabin noise and vibration control

Abstract

The use of the piezoelectric (PZT) actuator optimization for simultaneous aircraft cabin noise and vibration control is effective in reducing both noise and vibration. The study explores PZT elements into different control groups as means to simplify the control systems while increasing the control authority. A genetic algorithm is developed to optimize the noise and vibration separately and independently. By the application of Pareto cooperative optimization approach the present work can be extended to both noise and vibration reduction performance.
