In this paper, the flight control system of a flying-wing aircraft is designed. Significant dynamic nonlinearity and control redundancy are main problems for a flying-wing aircraft. As the over-actuated system and dynamic nonlinearity, the flight control system is divided into two parts: control laws and control allocation. Nonlinear dynamic inversion is used to design the control laws to generate...
Modeling aerodynamics of the separation aircraft is important for the controlling the separation aircraft. Using unstructured dynamic mesh method, coupled with Euler equation solver, unsteady flow-field solve give the real time aerodynamics to control model. Controlled by control law, the control surfaces as single moving bodies can deflect for attitude control. In time domain, through this simulate...
There is large time delay in `man-in-the loop' unmanned aircraft vehicle (UAV) system, especially for remote control flight by satellite communication. Time delay has great impacts on UAV and payload control, which can lead to the system unstable. Considering the character that the UAV was operated through man-machine interface, reference model based state predictive algorithm was proposed to solve...
The design of fight control is full of challenges because of the complex model and the complicated fight environment. The traditional control methods no longer ensure the demand in the many fight modes. Advanced control methods attract more and more researchers to make application research in this field. Adaptive critic design (ACD) is an effective control method to learn the optimal control online...
