Multi-model modeling method based on LPF algorithm

基于LPF算法的多模型建模方法

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).

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。

Under special conditions a BPF may also be used as an LPF or as an HPF.

在特殊条件下,带通滤波器也可以用作低通滤波器或高通滤波器.
