摘要:
为提高汽车用户的乘坐舒适性,进行基于层次分析法(AHP)和K均值聚类算法(KCA)的主动悬架控制研究.首先建立2自由度主动悬架模型,设计以悬架性能指标为目标函数的线性二次高斯(LQG)控制器;然后,利用AHP求得一组性能指标权值,并根据这组权值在MATLAB软件中得到225组新的权值;最后,在MATLAB/Simulink软件中进行主、被动悬架性能的仿真,通过KCA对权值分类分级.仿真结果表明:与被动悬架相比,采用AHP-KCA结合算法得到的主动悬架性能有所提高,尤其是车辆乘坐舒适性;与仅利用AHP相比,AHP-KCA结合算法进一步提升车辆悬架的性能,证明了其优越性.
Abstract:
In order to improve the riding comfort of automobile users, the active suspension control based on analytic hierarchy process(AHP)and K-means clustering algorithm(KCA)were studied. A two-degree-of-freedom active suspension model was established, and a linear-quadratic-Gaussian(LQG)controller with suspension performance indexes as objective function was designed. By using AHP, a group of performance indexes weights were obtained, according to which 225 groups of new weights were obtained in MATLAB software. The performance simulation of active and passive suspension was carried out in MATLAB/Simulink software respectively. The weights were classified and graded by KCA. The simulation results show that, compared with passive suspension, the performance of active suspension obtained by the combination of the two algorithms is improved, especially the riding comfort of the vehicle; compared with only using AHP, the combination of the two algorithms further improves the performance of vehicle suspension, which proves its superiority.
