Magnetic-levitation train static floating balance control parameter setting method, system, equipment and medium

Abstract

The invention discloses a method, a system, equipment and a medium for setting static floating balance control parameters of a maglev train, and the method comprises the steps: firstly obtaining a kinetic equation with enough multiple degrees of freedom according to a multi-body kinetic model of the maglev train, and then obtaining the suspension electromagnetic force of a single magnetic pole of a suspension electromagnet through mechanical calculation; the method comprises the following steps: firstly, establishing a typical single-magnetic-pole suspension control model, then extracting the typical single-magnetic-pole suspension control model to carry out PID feedback control parameter setting, then respectively establishing multi-point suspension control models of single suspension electromagnet modules of an end suspension frame and a middle suspension frame, carrying out multi-point magnetic suspension PID feedback control parameter setting, and finally carrying out static floating balance PID control parameter setting on the whole train. PID control parameter setting is carried out layer by layer from single to multiple and from simple to complex, so that the PID control parameter setting complexity of all levitation controllers in static-floating balance of the whole train is greatly reduced, and the static-floating shunting time is shortened.

Description

technical field [0001] The invention belongs to the technical field of maglev train control, and in particular relates to an electromagnetic suspension (EMS type) maglev train static-flotation balance control parameter setting method, system, computer equipment and storage medium. Background technique [0002] The maglev train system is a complex electromechanical system. The maglev train relies on the electromagnetic force generated by actively controlled electromagnets to levitate and guide, and relies on linear motors for traction and drive. The EMS electromagnetic levitation train is suspended on the track with a gap of about 8-10mm. The sensor installed on the electromagnet measures the levitation gap and the acceleration of the electromagnet in real time, and maintains the levitation gap at the rated value by actively controlling the coil current in real time. Due to the electromagnetic levitation train, the system itself is unstable. In order to achieve the stability ...
