摘要：

The present work considers the optimal placement of piezoelectric actuators on a thin plate using integer coded genetic algorithm. The fitness function reflects on the controllability index which is the singular values decomposition of a control matrix. The index measures the input energy required to achieve the desired structural control using piezoelectric actuators. The LQR (Linear Quadratic Regulator) optimal control scheme has been applied to study the control effectiveness. It is observed that the frequency responses of cantilever obtained from finite element code hold good in agreement with the experimental results. Numerical simulations revealed that optimal locations obtained by integer coded GA based on controllability index with LQR controller offers effective control as compared non-optimal locations.
