Abstract
Aiming at the problem of poor adaptability and lag of traditional braking control methods of high-speed train, a high-speed train braking information fusion method based on adaptive linear auto disturbance rejection is proposed to arrange the transition process for
Highlights
As high-speed trains have the characteristics of strong transportation, less time-consuming and low energy consumption, they have become one of the most effective means of modern transportation on a global scale and have attracted great attention [1]
Aiming at the modeling and speed tracking control methods involved in the braking system of high-speed trains, Hecquet et al.[4] the multi-dimensional modeling of the train in the braking system of high-speed EMU is carried out based on finite element analysis,and described the braking force and the EMU in detail.T
An adaptive linear active disturbance rejection control (ALADRC) is proposed to solve the problem of online real-time adaptive self-tuning of multiple parameters in the feedback link and the simplified expanded state observer link. , Thereby improving the braking control performance of high-speed trains
Summary
As high-speed trains have the characteristics of strong transportation, less time-consuming and low energy consumption, they have become one of the most effective means of modern transportation on a global scale and have attracted great attention [1]. The difference is that it can estimate and compensate for external disturbances and internal disturbances, overcome the shortcomings that PID requires an accurate model to set the control parameters, and eliminate the side effects produced by integral feedback It has the characteristics of high accuracy, fast response, and strong anti-interference ability, and has been widely used in military systems [13], power systems [14] [15], precision machining [16], etc. It has been found in a large number of practical applications that active disturbance rejection control can actively resist disturbances, improve system stability and control quality, and reduce control energy loss. An adaptive linear active disturbance rejection control (ALADRC) is proposed to solve the problem of online real-time adaptive self-tuning of multiple parameters in the feedback link and the simplified expanded state observer link. , Thereby improving the braking control performance of high-speed trains
