摘要
半主动悬挂控制是提高高速列车横向平稳性有效的方法。然而,车辆动力学模型的复杂性,用复杂模型设计出的控制器也是复杂的,且需要多个传感器对多个物理量进行检测,使其很难在实际车辆中应用。针对这一问题,提出一种有利于控制算法设计,又能反映车辆横向振动主要特点的3自由度简化模型和利于控制算法性能研究仿真的17自由度模型,用3自由度模型设计自适应预测控制算法,用17自由度模型进行仿真验证,有效解决了模型与控制的矛盾问题。
Semi-active suspension control is an effective method improve lateral stability of a high-speed train.However,it is extremely difficult to construct an accurate lateral dynamic model for a vehicle due to the complicacy of the dynamic model.Moreover,the controller based on the complicated model is also complex and various sensors should be employed to measure all kinds of physical parameters.All these limitations make it impossible to apply the complicated model into practical use.In order to solve the above problems,the authors put forward a simplified 3-degree-freedom model,which make it easy to design a control algorithm and can reflect the main characteristics of lateral vibration of a vehicle.Meanwhile,a 17-degree-freedom model is also presented which is good for studying and simulating the performance of the control algorithm.When adopting the 3-degree-freedom model to design adaptive predictive control arithmetic and using the 17-degree-freedom model to simulate for verification,the contradictory problem of modeling and control can be effectively solved.
