The invention relates to a high-speed magnetic suspension control method, controller, unit and system. The method comprises the following steps: acquiring a detection signal of a magnetic suspension control unit and a detection signal acquired by another magnetic suspension control unit in the same lap joint structure; diagnosing the two groups of obtained detection signals; if the two groups of detection signals do not have serious faults, outputting a control quantity by adopting a first control algorithm so as to control the current of an electromagnet coil; if the detection signal of the other magnetic suspension control unit has a serious fault, reporting a fault signal, stopping receiving the detection signal of the other magnetic suspension control unit, and outputting the control quantity by adopting a second control algorithm; and if a serious fault occurs in the detection signal, reporting a guarantee signal, and stopping the suspension control work. The method has the advantages that the train can be continuously in the stable suspension state, and the reliability of the suspension system is improved.
Description
technical field [0001] The present application relates to the field of maglev control, in particular to a high-speed maglev control method, controller, unit and system. Background technique [0002] Maglev technology refers to a technology that uses magnetic force to overcome gravity to levitate objects, among which maglev trains are the most well-known. In order to control the stable suspension of suspended objects, a reliable suspension system is required. [0003] The levitation system of the maglev train in the related art adopts the mode of overlapping structures, and each of the overlapping structures is provided with two levitation control units, the coupling relationship between the two levitation control units is strong, and each levitation control unit controls an electromagnetic The iron coil current jointly controls the suspension stability of the train. [0004] In view of the related technologies mentioned above, the inventor believes that when one of the two...
