Research on Modeling and Simulation of Aircraft Taxiing Rectification

For ideal condition, applied the same brake instruction signals to the aircraft right and left brake devices, the main wheels brake synchronously, and the aircraft doesn´t yaw. Whereas considering the side wind, the asymmetry of brake devices and the differences between tire and course coefficients, the aircraft may yaw. By analyzing the causations of aircraft deviation from the course during taxiing, the aircraft dynamic model with side wind is built, and a kind of differential braking control law based on slip ratio is proposed. Simulation results show that, by introducing this law the difference of brake tire velocities is eliminated, thereby aircraft can run along the correct course
