Abstract

In this work, a new optimization criterion is proposed for optimal placement of an actuator over a structure to generate desired vibrations. Linear quadratic tracking (LQT) control is used to generate desired vibrations. To solve optimization problem, genetic algorithm (GA) has been employed as an optimization technique. Proposed optimization criterion is applied on a simple two degrees of freedom system having a hypothetical actuator. Second order model of two degrees of freedom system is converted into a state space model. Thereafter, optimal tracking control law is applied on the state space model. Effect of location of an actuator on the performance of optimal control system is observed. It is found that by placing the hypothetical actuator at an optimal location suggested by GA, optimal control strategy is very effective in tracking the desired vibrations.
