Study On The Linear Parameterization Method For The Peak Friction Coefficient Of Aircraft Braking System

The aircraft braking is a complex dynamic and kinematic process, involving the brake wheel and runway status, loaded state and anti-skid control strategy and other aspects, including sophisticated uncertainties and nonlinear factors. This paper aiming at the nonlinear tire model with unknown parameters, combined with the empirical fitting slip rate coefficient curve based on the linear identification technology, design the optimal linear parameterization of runway based on coefficient curve identification algorithm and the estimated peak with equality constrained least squares coefficient estimation algorithm. The algorithm has the advantages of high estimation accuracy and simple calculation.
