电机械制动冲动限制控制研究

Research on Electromechanical Brake Impulse Limit Control

摘要: 电机械制动是一种采用电力作为动力源的新型轨道交通制动方式。在轨道交通行业内，列车冲动限制控制关系着行车安全和乘客的乘车体验，是列车制动控制中及其重要的一环。国内大部分城轨列车和高速动车组要求列车冲击率小于等于0.75 m/s³，按照该标准，本文通过PID控制对电机械制动装置进行力反馈控制，进行了电机械制动冲动限制控制研究，试验验证了电机械制动装置在列车冲击率小于等于0.75 m/s³等工况下的控制效果。

Abstract: Electro-mechanical braking is a new type of rail transit braking method that uses electricity as a power source. In the rail transit industry, train impulse limit control is related to driving safety and passenger experience, and is an important part of train braking control. Most urban rail trains and high-speed EMUs in China require the train impact rate to be 0.75 m/s³ or less. According to this standard, this paper uses PID control to perform force feedback control on electromechanical braking devices, and conducts electromechanical braking impulse limit control research. Then the control effect of the electromechanical braking device under the train impact rate of 0.75 m/s³ or less was verified by tests.
