Abstract
A levitation controller for magnetic levitation train is a dua-closed-loop control-regulation system composed of internal closed-loop and external closed loop. Said inteal closed-loop consists of bridge circuit composed of IGBTs, PWM waveform generator, current regulator, curren detector and the comparator for the output current of gap regulator and the detected current. Said external closed-loop comprises gap regulator, two actual gap signal processors, given gap signal-processed actual gas signal comparator, and electromagnet.
Description
Technical field
The present invention relates to a kind of suspension controller, particularly a kind of suspension controller that can guarantee the unsettled distance between suitable precision train and the ground rail.
Background technology
Suspend aerial during magnetic suspension train operation and ground rail disengages.No matter track upward slope, descending, keep straight on, turn round, remain the slit of certain vertical distance and horizontal direction between the train of high-speed cruising and the track.For this reason, a collection of magnetic pole is installed below train, its winding energising back produces magnetic field, train floats from ground by means of the effect of magnetic force, when the train high-speed cruising, the magnetic force that need make vertical pole makes the magnetic force maintenance train of slit magnetic pole and the left and right sides clearance constant between the track with the unsettled spacing between suitable high precision assurance train and the ground rail.This just needs a suspension controller, yet the difficulty of suspension controller is: the nonlinear relationship between electromagnet coil current value and the magnetic-field intensity is brought difficulty to regulating control; If is controlled object with the actual gap, the conference that adds of magnetic force makes the more and more littler and trend what zero in slit.
Summary of the invention
The purpose of this invention is to provide a kind of control electromagnet suspend aerial, but and the suspension controller of linear regulation hoverheight within the specific limits.
Technical scheme of the present invention is: a kind of suspension controller, be characterized in that it forms the electric current given value of bridge circuit ZBQ, pulse-width modulation waveform producer PWM, current relay LT and current detecting unit LB and slit regulating control output and comparator B by the detected current actual value of current detecting unit LB by IGBT
2Constitute current closed-loop and be interior ring and by slit regulating control FT, slit actual signal treater FB, slit actual signal detector FJ, crack, slit given signal δ g comparator B with after treatment slit actual signal
1And electromagnet L formation slit closed loop is two closed loop control control systems that outer shroud is formed.
Described electromagnet L places under-vehicle and track to constitute the gap, and energising forms a pair of magnetic pole, and described electromagnet L is connected with slit actual signal detector FJ, by the actual gap between slit actual signal detector FJ detection electromagnet L and the track.
Because the present invention realizes that current closed-loop has solved the nonlinear relationship between electromagnet coil current value and the magnetic-field intensity; Realized the slit closed loop, it is littler to have solved between track and the electromagnet gap, and slit actual value signal is also and then little, problem that can't closed loop.Make the slit that remains certain vertical distance and horizontal direction between the train of high-speed cruising and the track like this.
