基于MatlabSimulink对半主动悬架的Fuzzy-PID控制仿真研究

摘要

建立了2自由度1/4半主动悬架的数学模型,采用模糊控制和PID联合使用的模糊PID控制方法,利用MatlabSimulink对半主动悬架模型的各平顺性指标做了仿真分析,由仿真分析得出模糊PID控制方法可以有效地提高操作稳定性和行驶平顺性,并验证了模糊PID控制具有较好的自适应能力.%The paper first established a 2-degree of freedom 1/4 semi-active suspension mathematical model. Fuzzy control method combined with PID and fuzzy P1D control methods was adopted and MatlabSimulink was used for the analysis of the ride comfort indexes of the model. Results show that the fuzzy PID control method can effectively improve the operation stability and the running ride comfort, which verifies the adaptive ability of fuzzy PID control.
