In order to more accurate for nonlinear function extreme, this paper used improved particle swarm optimization neural network combining with genetic algorithm method to solve the problem. In view of the particle swarm optimization algorithm is easy to appear “premature” faults, introducing the adaptive threshold, initializing particles if they were under the constraint conditions, making particles...
The PID control as a popularly control method that is used in the control system, this control method is still adopted in many practical applications of the process currently. The paper mainly discusses the classical PID tuning methods, and on the basis of the method, which achieve a small unmanned helicopter longitudinal PID control parameters optimization by introducing the idea of genetic algorithm...
It has been proved that optimization of WVDF filter's coefficients using mathematical approaches can't converge to globally optimal coefficient weight vector. In this paper, genetic algorithm, which was proved that it was the most powerful unbiased optimization techniques for sampling a large solution space, is used to optimize WVDF filter's coefficients. By using the Stochastic Selection of parents...
