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。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 PLPE.
