Abstract: |
A PID neural network decoupling method based on genetic algorithm is investigated for aeroengine binary control system.Genetic algorithm is applied in training weighting factor of multilayered forward neural network.Thus the disadvantage of BP algorithm which would easily fall into partial extreme value can be overcome.The advantage of PID neural network controller includes simple structure and good dynamic as well as static performance.This method can be applied to the decoupling control of the multivariable system such as aeroengine. |
