Gust response stabilization for rigid aircraft with multi-control-effectors based on a novel integrated control scheme

For the higher performance demand of aircraft, the active control techniques of flight control system become more attractive. Among these approaches, the gust response stabilization has been more significant for the consideration of safety and comfort. Due to the constraint of the traditional control law, the parameter tuning process in a large envelope is very time-consuming and some special maneuvers can't accomplish by these designs. In order to overcome these defects of the conventional flight control laws, a new integrated nonlinear control scheme with modified active disturbance rejection control and real-time direct lift compensation control allocation technology is proposed. Its switched extended state observer can bring the observers to their full talents to estimate the signals. Aiming at taking full potential of the multi-control-effectors aircraft, two real-time linear control allocation methods for the transition from virtual control variables to actual control variables are also introduced. The simulation showed that this structure has good tracking performance and wind resistance performance.
