In order to solve the problem of unmanned combat air vehicle’s decoupling and robust performances, design an attitude controller for a certain type unmanned combat air vehicle. Combine with the dynamic inversion (DI) and quantitative feedback theory (QFT), use dynamic inversion to achieve the dynamic decoupling and ensure robust performance by means of quantitative feedback theory. Then carry out some simulation analysis with examples. Simulation results show that changes in the aerodynamic data within ±30%, DI + QFT controller can achieve precise control of the fighter attitude. The controller can solve the problem of aircraft attitude control and has a better engineering value
