Control system of magnetic levitation vehicle

Abstract

A control system of a magnetic levitation vehicle is applied to the technical field of magnetic levitation vehicles. The control system comprises a swing rod suspension system, a lateral variable damping buffer supporting system, a swing rod suspension feedback control system and a feedforward system. The swing rod suspension system comprises a swing bolster, a swing rod and a swing rod rubber support. The swing rod is connected with the swing bolster and the swing rod rubber support through a spherical hinge manner. The lateral variable damping buffer supporting system comprises the swing bolster, a transverse magneto-rheological damper and a lateral supporting seat. The transverse magneto-rheological damper is connected with the swing bolster and the lateral supporting seat through a spherical hinge manner. The feedback control system comprises a controller, a dip angle sensor fixed to the swing bolster, a swing rod weighing sensor fixed to the swing rod and acceleration sensors fixed to the lateral supporting seat and the swing bolster. The feedforward system comprises the controller, a clearance sensor of a guide electromagnet and a clearance sensor of a suspension electromagnet. The controller calculates the control current output to the damper according to sensor input, and vibration is reduced.

Description

technical field [0001] The invention relates to the technical field of maglev vehicles, in particular to a control system for maglev vehicles. Background technique [0002] The lateral vibration of the vehicle is positively correlated with the vehicle speed and the long-wave smoothness of the track. The high-speed maglev transportation system has high passenger-carrying speed, small turning radius and high curve passing speed, which determine that the high-speed maglev transportation system has higher requirements for vehicle stability than other vehicles. [0003] The existing high-speed maglev transportation system is under extreme conditions such as full-speed operation, small radius turning, and uneven settlement of track beams. The lateral vibration acceleration and vibration amplitude perceived by passengers in the vehicle are relatively large, and the comfort experience is not good. Existing vehicle suspension systems adopt a rubber spring passive lateral vibration r...

AI Technical Summary

Problems solved by technology

[0010] (1) The lateral vibration reduction system of the existing maglev vehicle is a passive vibration reduction system, which has weak ability to adapt to changing line systems, limited vibration reduction capability, narrow frequency response range, and poor passenger experience

[0011] (2) Due to the high coupling between the multiple suspension points of the maglev system and the different structure of the suspension system of the maglev vehicle, the existing single-point decoupling mode semi-active suspension vibration reduction control system in other industries cannot be applied to the high-speed maglev system
