Analyzing of Dynamic Friction Model for the Tire and the Runway

Abstract

A dynamic friction model which can be used in the aircraft anti-skid braking system is introduced. On one hand, this model has similiar steady-state characteristics compared with the static friction model, on the other hand, it captures transient characteristics of the tire and the runway in emergency braking control. Dynamics and characteristics of the tire and the runway are analyzed, the PID+PBM control law is designed in the aircraft braking system. Simulation results show that this dynamic model is feasible and effective, and the proposed model is accurate for description of the tire and the runway. It is a theoretical basis for the study and design of high performance aircraft anti-skid braking system.
