A dynamical compensating device for Weighting Sensor is designed based on genetic algorithms（GA） and functional link artificial neural network（FLANN）

in order to meet the demands of rapid weighing

combining the advantage of fast searching optimization of genetic algorithms and the advantage of better functional following of FLANN.Genetic algorithms is used to search the optimal link weights of FLANN.The simulation shows that the time of the step response and overshoot are reduced.The dynamical respond of the weighing sensor is approved effectively.And due to its simple algorithm can easily be realized

it has the practical value in practice.
