Optimal Design Method for Sensors/Actuators Placement in the Active Vibration Control of a 2 D Flexible Plate

摘要

It is of great importance for an active vibration control system to properly select its control gain parameters,and design optimally the placement of the sensors/actuators used in this system.Based on the principles of minimization of the total energy stored in the system,an optimal algorithm for sensors/actuators placement is put forward by improving genetic algorithms.In this paper,vibration control of 2 D flexible cantilever plate is studied using piezoelectric ceramic sensors/actuators.Numerical analysis shows that the proposed method is effective.
