摘　　要：在汽车系统动力学及汽车电控技术等车辆工程专业课程教学中,特别是有关车辆控制系统的实验教学中,因研究和控制对象比较复杂、控制效果不直观、学生参与度低、学生学习兴趣不高,造成教学效果不好。为此,以主动悬架控制为例,首先介绍了控制仿真中常用的动力学模型及其优缺点,然后以单轮1/4车辆模型为基础,探讨了随机线性最优控制器、模糊PID控制器的设计实现。整个过程可以让学生独立完成,仿真实验具有操作性强、学生参与度高,可显著地提高学生学习兴趣和教学效果。In the professional teaching of the vehicle engineering system dynamics and electronic control technology course,especially in the vehicle control system experimental teaching,because the research object is complicated,the control effect is not intuitive,students’participation is low,the students’interest in learning is not high,so the teaching effect is not good.Therefore,take the active suspension control as an example in this paper,the kinetic models used in the control simulation and its merits and flaws were introduced firstly.And then based on a quarter vehicle model with single wheel,the design and implementation of stochastic linear optimal controller and fuzzy PID controller were discussed.The whole process can make students complete independently,the simulation experiment has strong operability,high student participation,it can significantly put forward students interest in learning and teaching effectiveness.
