汽车电控空气悬架系统的控制策略研究
Research on Control Strategy research of automotive electro-controlled air suspension system
为了提高汽车的平顺性和操作稳定性，以某高档轿车前空气悬架系统为研究对象，给出了一种以车身高度、空气悬架刚度和阻尼为优化参数的综合控制策略。该策略对车身高度的调整进行模糊变积分PID控制，对悬架的刚度和阻尼的调整采用模糊自整定PID控制。在ADAMS软件环境下构建了1/4汽车空气悬架仿真模型，并利用MATLAB软件进行仿真。结果表明该综合控制策略与对刚度和阻尼的单纯控制策略相比，在汽车行驶时更具安全性和舒适性。
In order to improve ride comfort and handling stability of car, taking the front air suspension system of high-grade car as a research object. Given a comprehensive control strategy which by body height, the stiffness and damping of air suspension as optimization parameters. Body height takes fuzzy variable integral PID control in the strategy, the stiffness and damping use fuzzy self-tuning PID control. Established 1/4 mechanical model in ADAMS, doing simulation with MATLAB. The results show that compared with stiffness and damping control, comprehensive control make the car more safe and more comfortable.
