The Adaptive Control of Aircraft Brake Based on Asymmetric Barrier Lyapunov Function

Considering the complexity, non-linearity and uncertainty of aircraft antiskid control system, the author takes such shortcomings of traditional “PD + PBM” control methods into account as low braking efficiency and deep skidding on hybrid runways, and puts forward the constraint control algorithm of slip rate based on asymmetric barrier Lyapunov function, which meets the purpose of adaptive full-regulation from the concept of system integration that the slip ratio is also satisfied in the stable region where it is constrained, so as to improve the braking efficiency. By comparing with the simulation results of the traditional “PD + PBM” control algorithm, the author tries to show that the braking process has a good follow-up performance and a smooth brake curve, which avoids the problem of low-speed skidding, optimizes the braking performance and improves braking efficiency based on adaptive control algorithm of slip rate constraint.
