Research on fault of suspension system in permanent magnetic and electromagnetic hybrid high speed maglev train
Prognostics and System Health Management Conference（2014）
Abstract
This paper studies the suspension control problem of permanent magnetic and electromagnetic hybrid high-speed maglev train under different fault condition. The suspension system model with joint structure is established. The linear quadratic optimal control theory is applied to implement the control algorithm design. The simulation analyzes multiple possible failure conditions of the joint joint structure in the practical work. At the same time, the paper considers the power interference and the disturbance existing in the actual operation, gets the constraint conditions of normal work of the joint structure under different conditions when it has fault, which provides a basis for the safety strategy in the fault handling of the suspension system.
