摘　　要：该文以某飞机机型为研究对象,对液压刹车系统的建模、控制方法以及系统仿真作了深入的研究。在考虑飞机防滑刹车系统的特点和各组成部分物理特性的基础上,建立了系统仿真的整体数学模型;采用PBM控制思想完成了控制回路的设计,并在MATLAB6.1/SIMULINK仿真环境下进行了系统仿真分析与研究。另外给出了干、湿两种跑道的仿真结果,并进行了刹车性能的比较分析。该文的仿真结果曲线与真实刹车物理试验曲线基本吻合,从而证明了建模的合理性。所进行的数字仿真也为刹车系统的设计和研究提供了一定的理论依据。With the background of a certain aircraft,the article makes a deep investigation on the modeling of hydraulic braking system, control method and system simulation. Based on the feature and physical characteristics of anti - skid braking system, the mathematical models of system simulation are set up. PBM control method is proposed in designing cybernetics. The simulation analysis and research are performed on the Matlab6.1/Simulink platform. Besides the paper gives the simulation results of dry runway and wet runway and makes an analysis on braking performance. Research shows that the result curves of simulation are consistent with the physical test curves, and the modeling of system is reasonable. Digital simulation also provides important gist for design and research of braking system
