Hypersonic vehicle is a complex systems with strong coupling, highly nonlinear, a large uncertainty. The adaptive fuzzy control method is applied to the attitude control of the longitudinal channel. Dividing the system into inner and outer cycle, the feedback control law is designed for the longitudinal channel of hypersonic vehicle. Fuzzy function is used to approach nonlinear function in the hypersonic...
This paper analyzes the working principle of grate cooler system and the main factors that affect the efficiency of grate cooler system. By applying the improved BP(back propagation) algorithm in neural network modeling, make the neural network predicts the grate chamber pressure, then modify the grate speed value that obtained by the fuzzy controller to control the grate chamber pressure. The field...
