| 摘 要： | 针对保证无人战斗机控制器的解耦性能和鲁棒性能问题,设计一个某无人战斗机的姿态控制器。将动态逆(DI)和定量反馈理论(QFT)相结合,用动态逆实现无人战斗机控制的动态解耦,用定量反馈理论保证控制器的鲁棒性能,并以实例进行仿真结果分析。仿真结果表明:在气动数据变化±30%的范围内,DI与QFT控制器可以实现对飞机姿态的精确控制,能很好地解决飞机的姿态控制问题,有较好的工程应用价值。

| Abstract: | 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. |
