Robust control for aircraft anti-skid braking system based on dynamic tire/road friction force model
The aircraft anti-skid braking system plays an important role for the safety during taxiing.Aircraft tire/road friction force is essential information for model based control law.In this paper,a robust control strategy with an observer-based dynamic aircraft tire/road model is given to improve the brake quality.Firstly,the nonlinear fuselage and wheel models are derived.The tire/road friction force is derived with LuGre dynamic friction model considering velocity correlation,in which the internal friction state is estimated by dual-observer.In case of external disturbance and modeling error,a robust controller is employed to track the online calculated desired slip rate.The simulation results show that the well-designed controller has stable brake performance.
