非线性PID控制算法在重型车辆ABS中应用的仿真研究

Simulation Research on Application of A Nonlinear PID Algorithm in Heavy Vehicle ABS Problem

提出一种新型的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 solve heavy vehicle ABS （Anti-lock Brake System） problems. The NPID algorithm combines the advantages of robust control and easy tuning. Simulation results at various situations by using TruckSim show that NPID controller has shorter stopping distance and better velocity performance than the conventional PID controller.
