摘　　要：以Matlab仿真软件为平台研究并建立了汽车制动器试验台计算机控制的积分方程模型、能量守恒模型、差分方程模型,确定了每一离散时间段驱动电流与主轴力矩的关系。用曲边梯形的面积代替积分的思想进行了能量误差分析,设计了各种模型的计算机控制方法,并根据风阻和轴承摩擦以及其它阻力形式的消耗的影响,对各控制模型进行了相应的修正,从而提高了计算机控制的精度,为检验汽车制动器设计的优劣和检测制动器的综合性能提供了有效的方法。Based on the Matlab simulink software,we research and establish integral equation model,energy conservation model and differential equation model for control method of automotive brake test-bench.By these models we can work out drive current and establish the relationship between drive current and spindle torque,moreover determine the dynamic relationship of the drive current for each discrete period.Using the area of curved trapezoid instead of integration for energy error analysis,design computer-controlled method for each model and amend each model accordingly,thus improving the accuracy of computer control,and providing an effective method for testing the merits and integrated performance of automotive brake design.
