高超声速飞行器的模糊预测控制
Fuzzy hypersonic flight control with prediction model
摘要
Abstract
An adaptive fuzzy controller using prediction model was proposed to simplify the existed back-stepping design for the longitudinal dynamics of hypersonic flight vehicle.For the altitude subsystem,an explicit four-step ahead prediction model is derived from the original dynamics.Only one fuzzy logic system is needed to approximate the system uncertainty and in this way it avoids the repeated calculation of the virtual control.The system tracking error is guaranteed to be ultimately uniformly bounded via stability analysis.Compared with back-stepping scheme,the controller is considerably simpler.Simulation is presented to show the effectiveness of the proposed control approach.关键词
