基于磁流变液的电控转向阻尼器的控制系统建模

Modeling of Electro-controlled Steering Damper Based on Magnetorheological Fluid

对基于磁流变液的电控转向阻尼控制器进行了系统介绍,建立了控制系统的状态空间表达式,通过对模型的状态空间进行分析,提出通过状态增益反馈矩阵将系统控制性能调节到理想状态的方法,并建立了控制系统基本控制策略。由于系统为非线性时变系统,所以在控制策略的制定中必须考虑车速对系统参数的影响。

The paper introduces the electro-controlled steering damper based on magnetorheological fluid,and establishes the control system＇s state space expression.Through the primary analysis to the model,the method that adjusts the control system＇s performances to ideal state through a state gain feedback matrix is proposed.And then the basical controll strategy is established.Because the system is nonlinear and time variale,the influence of the vehicle＇s speed to the system＇s parameters should be considered when establishing the control strategies.
