摘要: 从力学与非线性控制理论综合应用的观点出发,对机轮滑行制动过程中制动力矩的控制问题进行了理论分析与研究,提出了一种新的制动力矩加、卸载解析条件表达式。通过对机轮制动时机轮-地面系统力学模型的动力学仿真,定性地描述了具有此种制动力矩控制方式的防滑制动系统动态特性

Abstract: Based on the view of combining nonlinear mechanics with modern control theory, a study is carried out on the control of braking moment for a wheel and tyre during its taxiing and braking. A new analytical expression is proposed for the increasing or decreasing condition of braking moment . With the dynamic simulation on the mechanical model described in the paper, the dynamic properties of the antiskid braking system(ABS) on the condition as stated above are illustrated qualitatively .

Key words: antisk id braking system, braking momene, variable structural control
