【摘要】 通过3自由度车辆半主动悬架系统模型的建立,应用模糊控制理论并结合模块化思想,进行了模块化半主动悬架模糊控制器的设计,并在MatLab/Simulink环境中对其进行了仿真,把它与被动悬架和用LQG控制器控制的半主动悬架作了比较。仿真结果表明,相对于其它两种悬架,具有模块化模糊控制器作用的半主动悬架在降低人体的加速度、改善车辆的乘坐舒适性和平顺性上有显著的效果。更多还原

【Abstract】 Establishing a 3-DOFs of vehicle model with semi-active suspension, integrating the fuzzy logic control theory with the modular thought, modular fuzzy logic controllers of the semi-active suspension were designed. It was simulated in the environment of Matlab/Simulink and compared with the conventional passive suspension and the suspension with a LQG controller. The results demonstrate that the semi-active suspension with the modular fuzzy logic controllers has good effect on decreasing the body’s acceleration and it has improved vehicle’s riding performances.更多还原
