This paper provides a rigorous steps for controller design of a novel ducted fan vehicle under actuator uncertainties and saturation. Considering uncertain actuator dynamics, a control-oriented model is proposed to provide convenience for practical control applications. A structured robust controller that stabilizes the vehicle in the presence of actuator uncertainties and external disturbances is...
We propose the structured two-loop flight control system of a novel tandem ducted fan vehicle for near hover flight in consideration of actuator saturations on its dynamics. The prescribed controller architecture consists of static output feedback inner loop and four PI outer loop, which is a desirable and intuitive structure for practical implementation. The effect of a limited control activity on...
In this paper, one robust adaptive controller is proposed for hypersonic flight dynamics with high gain observer (HGO) and neural networks (NNs). For the attitude subsystem, it contains flight path angle, pitch angle and pitch rate. To avoid the complex back-stepping design, the dynamics are transformed into the normal feedback form. With HGO estimating the newly defined states, the controller is...
