Fuzzy CMAC control design for an airbreathing hypersonic cruise vehicle

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 an airbreathing hypersonic cruise vehicle (AHCV) which has an integrated airframe-propulsion system configuration. A set of nonlinear longitudinal equations of motion for the vehicle which include 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.
