The present application relates to a high-speed maglev control method, controller, unit and system. The method includes obtaining the detection signal of the maglev control unit itself and the detection signal collected by another maglev control unit in the same overlapping structure; If there is no serious fault in the two sets of detection signals, the first control algorithm is used to output the control quantity to control the current of the electromagnet coil; if the detection signal of another maglev control unit has a serious fault, report the fault signal and Stop receiving the detection signal from another maglev control unit, and use the second control algorithm to output the control quantity; if there is a serious failure in the detection signal of itself, report the guarantee signal and stop the suspension control work. The application has the effect of helping to keep the train in a stable suspension state and improving the reliability of the suspension system.
Description
Technical field [0001] The present application relates to the field of maglev control, in particular, to a high speed magnetic floating suspension control method, controller, unit, and system. Background technique [0002] Maglev technology refers to a technique that utilizes magnetic to overcome gravity to suspend objects, wherein the maglev train is most well known. In order to control the stable suspension of the suspension object, a reliable suspension system is required. [0003] The magnetic suspension train suspension system in the related art uses a lap structure, and each of the two suspension control units are provided inside each lap structure, and the coupling relationship between the two suspension control units is strong, and each suspend control unit controls one electromagnetic. The iron coil current is controlled by the suspension of the train. [0004] For the related art in the above, the inventors believe that the suspension stability of the train is suspended...
