摘要
基于简化的高速列车的半主动悬架模型,以DSP2812为核心控制板,建立磁流变(MR)阻尼器的模糊控制系统.通过在Matlab/Simulink中建立仿真模型,比较模型在模糊控制和被动控制下的减振效果.模型验证可行后,利用代码自动生成技术实现控制系统的软件设计,并将代码下载到DSP控制板上,完成整个控制系统的设计.在简化的高速列车半主动悬架试验平台上进行模糊控制和被动控制试验,试验结果表示模糊控制效果优于被动控制.
The fuzzy control of magnetorheological damper(MRD)was established,using simplified high-speed train as semi-active suspension model,and code control board as DSP2812.Simulation model was established in Matlab and meanwhile the damping effect of fuzzy control and passive control were compared.After the model was tested to be right,the software design of control system was achieved,using automatic code generation technology,and the code was downloaded to the DSP control board,complete the entire control system design.Fuzzy control and passive control experiments were carried out on the semi-active suspension test platform of the simplified high-speed train.The results show that fuzzy control is better than passive control.
