摘要:
针对传统车身高度调节方法导致的闭环空气悬架系统较大俯仰角问题,提出两种不同车身步进控制算法,得到各个空气弹簧的目标高度.利用比例-积分-微分(PID)控制器对电磁阀的电流信号占空比进行调节.将提出的两种控制算法在MATLAB/Simulink进行实现,并与AMESim平台上建立的空气悬架模型进行联合仿真.仿真结果表明:两种算法都能减小车身高度控制过程中造成的俯仰角,且第二种步进控制方法的效果更优.
Abstract:
To deal with the problem about a large pitch angle caused by using the conventional height adjustment method in a closed-loop air suspension system, two different step control algorithms were presented to determine the target height of every air spring, and then a proportional-integral-derivative(PID)controller was used to adjust the duty ratio of valves’ electric current signals. The proposed algorithms were implemented in the MATLAB/Simulink and then co-simulated with the air suspension model built on the AMESim platform. The simulation results indicate that both of two algorithms have an obvious effect on the reduction of pitch angle, and the second step control algorithm performs better.
