Embodiment Construction

[0048] figure 1 It is a schematic diagram of the modular bogie structure used in the EMS low-speed maglev train. Each car has four suspension bogies, and each bogie is composed of two suspension modules on the left and right, and the modules are connected by anti-roll beams. Each module is equipped with four suspension electromagnets, and the four electromagnets are divided into two groups along the traveling direction of the train, each group contains two electromagnets, and the two electromagnets in the group are connected in series, which is equivalent to a single electromagnet.

[0049] figure 2 It is a structural schematic diagram of the suspension control system in the single electromagnet control method commonly used at present. The suspension control system is composed of a suspension sensor group A, a suspension controller A, a suspension chopper A, a suspension sensor group B, a suspension controller B, a suspension chopper B and a vehicle monitoring system. The ...

Abstract

A module levitation control method for the frequently conducting electromagnetic-type low-speed magnetic levitation train features that a levitation control system has only one levitation controller consisting of signal processing unit, A/D converter, clock signal generator, master DSP unit, PWM wave generator and auxiliary DSP unit. Said method includes such steps as measuring the levitation states of ends A and B of a module by two levitation sensors, calculating their control values, and controlling the current values of electromagnets A and B and in turn their electromagnetic forces, so ensuring the gap between module and track to be constant.

Description

technical field [0001] The invention relates to a levitation control method for a maglev train, in particular to a module-based levitation control method for a low-speed maglev train (Electro Magnetic Suspension, referred to as EMS). Background technique [0002] EMS maglev 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. Much attention. The electromagnet and track of the EMS low-speed maglev train constitute the suspension system of the train. This system is an unstable system, and the stable suspension of the train can only be realized through feedback control. The suspension performance mainly depends on the suspension control method. The key to the suspension control method is to design a suspension control system. The suspension control system controls the magnitude of the electromagnetic force by controlling the current of the electromagnet according to ...
