随着社会的发展,大部分人在经济水平能力上已经拥有了汽车,但是人们希望汽车在性能方面可以实现稳定性高以及持久性强的优点,决定这些优点是否可以实现的一个重要因素就是悬架。本文通过采用MATLAB软件,分析了模糊控制器和PID控制器性能,建立了关于汽车二自由度数学模型,仿真软件是基于SIMULINK,仿真结果显示汽车半主动悬架上控制效果PID控制器逊于模糊控制器。
With the development of society, most people already own cars with the economic level capability. However, people hope that the automobile can achieve the advantages of high stability and high durability in terms of performance. An important factor that decides whether these advantages can be achieved is that the suspension frame. In this paper, MATLAB software was used to analyze the performance of fuzzy controller and PID controller. The mathematic model of two-degree-of-freedom automobile was established. The simulation software was based on SIMULINK. The simulation results showed that the PID controller of semi- Controller.
