On Aircraft Antiskid Brake System Based on Fuzzy Neural Network

To prevent serious skidding and obtain maximum friction coefficient, a design of intelligent aircraft antiskid brake system is presented. The controlling algorithm is improved by employing some intelligence methods. The neural network BP algorithm is used to get the real-time perfect slip ratio, and the fuzzy neural network(FNN)method is used to follow up with the target slip ratio. The intelligent control is realized by using the circuit based on digital signal processor (DSP). The result shows that the aircraft antiskid braking performance improves distinctly and the robust increase obviously.
