重型车辆防抱死系统控制算法仿真研究

Emulational research of control algolithm for ABS system of heavy vehicle

文章提出了一种新型的NPID非线性控制算法,并将其应用于重型车辆ABS(防抱死制动系统)问题中。NPID算法不仅鲁棒性强,而且参数便于整定。使用仿真软件TruckSim,在各种情况下的仿真结果显示,相对于常规的PID控制器,NPID控制器具有更短的制动距离和更好的速度表现。

A new NPID （Nonlinear Proportional- Integral- Differential） control algorithm is applied to heavy vehicle ABS （Anti- lock Braking System） . The NPID algorithm combines the advantages of robust contrul and easy tuning. Simulation results at various situations using TruckSim show that NPID controller has shorter stopping distance and better velocity performance than the conventional PID controller.
