摘　　要：由于采用机体一体化设计,吸气式高超声速飞行器的气动特性难以准确获知,建立的数学模型是极不准确的;设计了一种模糊CMAC神经网络(FCMAC)控制器及其学习算法,在CMAC神经网络控制器中结合模糊逻辑理论,使得CMAC控制器具有自学习能力;仿真用高超声速飞行器的纵向模型对该控制器进行了验证,证明该控制方法能够有效地跟踪飞行器的高度和速度指令。This paper proposes the implementation of fuzzy cerebellar model arithmetic computer （FCMAC） neural network for altitude and velocity tracking control of the longitudinal model of hypersonic vehicle which has an integrated airframepropulsion system configuration. A set Of nonlinear longitudinal equations of motion for the vehicle which inelude the CFD--generated aerodynamic, propulsion, and coupled aero propulsion data are developed. A FCMAC controller and its learning arithmetic are designed according to the feature of the hypersonic cruise vehicle. Simulation results demonstrate the effectiveness of FCMAC control design in tracking altitude and velocity commands.
