摘　　要：随着轨道列车智能化、绿色能源和“双碳”目标的实施与发展,列车电机械制动系统以其精度高、响应快、能耗低、噪声小等特点,优于传统电空制动系统。目前,国内外对于轨道列车电机械制动系统的控制性能研究较为匮乏,存在非线性摩擦影响因素、狭小空间无法加装测试传感器等难点。文章针对压力传感器低耐久度、高成本的问题,提出了制动力观测器的控制策略。文章建立压力控制数学模型,设计了基于制动力观测器的自抗干扰控制器,并进行了仿真与试验验证。结果表明,制动力观测器模式条件的控制精度能够满足运用要求,验证了控制算法的有效性。With the development of rail trains towards intelligence and green energy and the implementation of the dual-carbon goals,the electro-mechanical braking system has been considered superior to the traditional electro-pneumatic braking system due to its multiple advantages,including high precision,fast response,low energy consumption,and low noise.However,research on the control performance of electro-mechanical braking systems for rail trains is insufficient both in China and abroad,due to challenges such as nonlinear friction-influencing factors and the difficulty of installing testing sensors within the limited space available.This paper proposed a control strategy using a braking force observer,with a focus to address the issues of low durability and high cost associated with pressure sensors.A mathematical model for pressure control was established,and a self-anti-jamming controller based on a braking force observer was designed,which was subsequently verified by simulations and experiments.The results show that the control accuracy under the conditions of the proposed braking force observer mode satisfies the application requirements.Additionally,the effectiveness of the control algorithm is verified.
