Embodiment Construction

[0093] The present invention will be further described below in conjunction with the accompanying drawings.

[0094] Such as figure 1 As shown, a fault diagnosis and fault-tolerant control device for a train active suspension system based on a dynamic actuator includes a dynamic actuator fault injection module 1, a platform control module, a fault diagnosis module, a real-time monitoring module 10 and a data acquisition module 9. The dynamic actuator is an electromagnetic actuator. The fault injection module of the dynamic actuator is connected with the platform control module, and the simulated fault information is provided to the platform control module, and the fault characteristics are displayed through the platform control module. The platform control module passes the data acquisition module The measured displacement information, speed information and acceleration information are transmitted to the fault diagnosis module, the fault diagnosis module is connected with the ...

Abstract

The invention discloses a train active suspension system fault diagnosis and fault-tolerant control device and a train active suspension system fault diagnosis and fault-tolerant control method based on a dynamic actuator, and belongs to the technical field of automatic control. The train active suspension system fault diagnosis and fault-tolerant control device based on the dynamic actuator comprises a dynamic actuator fault injection module, a platform control module, a fault diagnosis module, a real-time monitoring module and a data acquiring module; and the dynamic actuator adopts an electromagnetic actuator. By the online parameter estimation and adaptive robust fault-tolerant control method based on the dynamic actuator, limitation of the traditional fault diagnosis device under the condition that outside disturbance exists and faults of a plurality of actuators occur synchronously is avoided. The train active suspension system fault diagnosis and fault-tolerant control device and the train active suspension system fault diagnosis and fault-tolerant control method based on the dynamic actuator are easy to operate and high in implementability, and can be used for verifying feasibility on fault diagnosis and state monitoring of a train active suspension system actuating mechanism.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a device and method for fault diagnosis and fault-tolerant control of a train active suspension system based on a dynamic actuator. Background technique [0002] The train suspension system plays an important role and significance in supporting the car body and bogie of the train, isolating the force exerted on the wheels caused by track irregularities and controlling the attitude of the car body related to the track surface to provide a comfortable ride quality. [0003] According to the different control forms, the suspension system is roughly divided into three categories: passive suspension system (fixed spring, damping structure), semi-active suspension system (spring, variable damping structure) and active suspension system (spring, damping, actuator structure) . Passive suspension has simple structure, low design difficulty, low price and high reliability, but b...
