Optimal dynamic control for a maglev vehicle moving on multi-span guideway girders

Popis výsledku v původním jazyce

An optimal control algorithm using a virtual tuned mass damper called virtual TMD to control the levitation force of a magnetic system is developed for resonance suppression of a maglev vehicle moving on multi-span guideway girders. Since the optimal dynamic parameters of a TMD in vibration control are well developed, the optimal tuning gains required to control the magnetic oscillations of the maglev bogie can be directly used and fed back to the maglev control system. To address the dynamic interaction analysis from the maglev vehicle to the guideway girders and vice versa, the entire coupling system is decomposed into two subsystems, one is the moving vehicle subsystem and another the stationary guideway subsystem. Then, an incremental–iterative procedure associated with the Newmark method is presented to solve the twonsets of subsystemequations. Finally, the control effectiveness and parametric studies of the optimal virtualTMDscheme on resonance reduction of the moving maglev vehicle are demonstrated.
