【摘要】 建立了汽车主动悬架与转向控制系统半车集成模型,应用模糊逻辑控制理论,提出一种带参数的自调整模糊方法,设计了汽车主动悬架与转向系统模糊参数自调整集成控制器,该控制系统当偏差变小或变大时,调整因子总能确保系统稳定,适合工程应用。通过对汽车主动悬架与转向控制系统试验仿真表明,实行模糊参数自调整集成控制后,汽车的整车平顺性、操纵稳定性和安全性等综合性能指标明显优于汽车主动悬架与转向系统LQG集成控制。更多还原

【Abstract】 Through established the integrated control model of vehicle active suspension and steering system,adopting fuzzy logic control theory,a self-adaptive fuzzy method with parameter was put forward,the self-adaptive fuzzy rule controller of integrated vehicle active suspension and steering system was designed.When the errors become large or small,the adjustment gene always insure the system stability,suit for engineering applications.Through simulation of the controller,compared the controller with the integrated vehicle active suspension and steering LQG control system,the performance of steering smooth,control stabilization and security are all distinct improved.更多还原
