Fuzzy Neural Network Controller Based on Hybrid GA-BP Algorithm

摘要

This paper presents a hybrid GA-BP algorithm for fuzzy neural network controller (FNNC). BP algorithm is a method to monitor learning, easily realized and with good local searching ability. But it depends too much on the the initial states of the network. Genetic algorithm is a random search algorithm which has strong global searching ability. The hybrid GA-BP algorithm ensure the global convergence of learning by genetic algorithm, overcomes the BP algorithm's dependency on the initial states on the one hand. On the other hand, combined with the BP algorithm overcome the simple genetic algorithm's randomness, improve the searching efficiency. The simulations on the inverted pendulum problem show good performance and robustness of the proposed fuzzy neural network controller based on hybrid GA-BP algorithm.
