Paper Abstract

The present work considers with the optimal placement of piezoelectric actuators on a thin plate via modified control matrix and singular value decomposition (MCSVD) approach using Modified Heuristic Genetic Algorithm (MHGA). Optimal placement of piezoelectric actuators is investigated to suppress the first six modes on cantilever plate. Vibration suppression has been studied for cantilever plate with piezoelectric patches in optimal positions using LQR (Linear Quadratic regulator) scheme. It is observed that developed present approach has given the greater closed loop damping ratio and lesser computational requirements.
