Abstract
The multiobjective task of optimal control of vibration response of an elastic plate is considered. An application of a genetic algorithm for determination of the optimum compensating force frequency dependence and parameters of concentrated masses for different boundary conditions is described. The principle of virtual work and Ritz approach are employed for investigation of dynamic behaviour of mass-loaded plates, which are subjected to any number of forces. The optimisation problem is formulated as a constrained task. Optimization provided the reduction of both total acceleration level and compensating force. Numerical results show the appropriateness of the model for optimization of concentrated masses values and their location on a plate. Interpolation of optimal compensating force parameters frequency dependence is used for the design of feedforward control system.
