Abstract

Prediction methods for the proper positioning and optimal number of actuators are necessary for efficient structural vibration control. The method proposed can provide ideas on how to select the optimum positions and number of the actuators. Using the coupled mode optimal control algorithm and comparing the control results of each given system, these methods are implemented. As a control structure, an all-clamped thin square plate with proportional damping has been selected. Some possible control algorithms that can be applied to the distributed structural system are discussed. To decide the control gain, a steady-state quadratic optimal control algorithm and discrete-time control system have been used. Since 6 plate modes are considered in the control system, a 12 X 12 matrix form of the system equation can be set up. By changing the impulse and the actuator positions and the number of actuators, a series of mode control simulations have been tried, and on the basis of these results, optimal actuator number and positions can be obtained.
