【摘要】 传统单质点模型无法准确反应列车运行过程中所受到的复杂路况的影响,为解决此问题,本文设计了一种考虑列车长度的高速列车模型。同时为实现控制器的快速准确控制,采用了一种终端滑模控制策略,为解决滑模控制的抖振现象,引入了自适应模糊控制策略,对切换项进行模糊化,使其切换项连续化,最终设计出了自适应模糊终端滑模控制器。仿真结果表明,本文设计的模型相较于传统单质点模型,可以相对准确描述列车运行过程所受的附加阻力影响,本文设计的控制器可以对预期速度实现精确跟踪,同时具有较好的抗干扰能力。更多还原

【Abstract】 The traditional single mass point model cannot accurately respond to the complex road conditions that the train is subjected to during operation.To solve this problem,a high-speed train model considering the train length is designed in this paper.At the same time,in order to achieve fast and accurate control of the controller,a terminal sliding mode control strategy is adopted.Meanwhile,to solve the jitter phenomenon of the sliding mode control,an adaptive fuzzy control strategy is introduced to fuzzify the switching term and make its switching term continuous,and finally an adaptive fuzzy terminal sliding mode controller is designed.Simulation results show that the model designed in this paper can relatively accurately describe the complex environmental influence on the train operation process compared with the traditional single mass point model,and the controller designed in this paper can achieve accurate tracking of the expected speed and at the same time has better anti-interference capability.更多还原
