| 摘 要： | 建立了四通道车辆防抱制动系统（ABS）的状态空间模型，考虑到其非线性特性，提出了用PLPF（分段线性多项式）函数对其进行分段线性化的方法，并提出了修正的PLPF方法，利用车辆系统的状态参数得出系统矩阵和控制矩阵。用最优控制方法得出在下一个采样点时的车辆状态，即可按照基于PLPF的最优控制方法得到控制序列。

| Abstract: | A state space model for ABS(Anti-lock Brake System) of four channels was set up.Considering the nonlinear characteristics of its control problem,a piecewise linear superposition system was built by PLPF(Piecewise Linear Polynomial Function).Since the subsequent state of a vehicle system was undetermined,a modified PLPF method was proposed for ABS control.System matrix could be determined utilizing parameters of a vehicle state of two time points,and control series could be determined accordding the optimal control based on PLPF. |
