Suspension control method and device for ems type low-speed suspension train

Abstract

The invention discloses a suspension control method and device used for an EMS type low-speed suspension train. The suspension control method includes the following steps: respectively collecting clearance signals, acceleration signals and current signals of sensor groups, enabling the clearance signals, the acceleration signals and the current signals of the two sensor groups corresponding to a same suspension module to be combined to calculate to obtain two suspension control variables, and enabling the two suspension control variables to serve as feedback to control electric currents of two single electromagnets of the suspension module to guarantee that the suspension clearance between the suspension module and a track is kept constant. The suspension control device comprises the first sensor group, the second sensor group and a suspension controller. The suspension controller comprises a suspension control board, a first suspension chopper and a second suspension chopper. According to the suspension control method and device, the defect, which can not be really overcome by a current single-point suspension control method, that two points inside the suspension module influence each other can be overcome, the number of the single-bogie suspension controller is reduced, the mass of the suspension controller is lightened, the manufacturing cost of the suspension controller is reduced, and the reliability of the suspension controller is improved.

Description

technical field [0001] The invention relates to the field of high-speed suspension trains, in particular to a suspension control method and device for EMS (Electro Magnetic Suspension, EMS for short) low-speed suspension trains. Background technique [0002] EMS (Electro Magnetic Suspension, referred to as EMS) low-speed suspension train is a new type of vehicle that relies on the attraction between the electromagnet installed on the train and the track to make the train suspend on the track. , No pollution and other advantages have won more and more attention. The electromagnet and the track of the EMS low-speed suspension train constitute the suspension system of the train. This system is an unstable system, and the stable suspension of the train must be realized through feedback control. The suspension performance mainly depends on the suspension control method. The key to the implementation of the suspension control method is to design a suspension controller. The contr...
