In order to grasp the complexity of the hypersonic vehicle dynamic characteristics, create its reliability control model, for the mathematical model of hypersonic vehicles is highly nonlinear and strong coupling, introduced the object-oriented modelling method, design a neural network, Petri control algorithm based on characteristics model, the mathematical model of the nonlinear is transformed into the equivalent linear model with control design requirements. And through the appropriate transform, design of the hypersonic vehicle dynamic inversion control system, building performance prototype reliability model based on Petri net, can stabilize the system, get decoupled affect purposes. Simulation results show that the performance digital mock-up reliability model is high accuracy, robustness, anti-jamming capability, has a good dynamic and steady-state performance.
