【摘要】 研究路面粗糙度扰动作用下的非线性汽车主动悬挂系统的最优减振控制问题。首先建立了二自由度四分之一非线性悬挂系统和路面粗糙度扰动模型。然后运用逐次逼近方法设计主动悬挂系统的前馈-反馈最优减振控制律。最后通过构造状态观测器解决前馈补偿器的物理不可实现问题。仿真示例验证了所设计的最优减振控制律的有效性。
【Abstract】 The problem of optimal vibration control for vehicle active suspension systems under road roughness disturbance is considered.Firstly,the nonlinear models for two-degree-freedom quarter-car suspension system and road roughness disturbance are built.Then,based on the theory of successive approximation approach(SAA),the nonlinear optimal control law is designed.A state observer is constructed to make the feedforward compensator physically realizable.Numerical simulations illustrate the effectiveness of the optimal control law.
