Method for voltage control of the magnets of a MAGLEV train, and associated controller

This method serves to control the voltage of the magnets of a MAGLEV train. At least three status variables are used which are acquired in an observer on the basis of the measurement variables for the magnet gap width s and the magnet acceleration b. In order to improve the follow behaviour of the MAGLEV vehicle without increasing the noise portion, a rail signal is additionally fed to the controllers of the individual magnets, the said signal being acquired in each case by a rail observer (20) from the measurement variables s and b of one of the magnets (j-k) lying ahead in the direction of travel. This is effected in that the said signal constitutes a noise-free rail signal u which is in phase in the useful frequency range with respect to the magnets j lying respectively behind. Different controllers for carrying out the method are presented. ...

Apparatus for controlling a magnet in a magnetically suspended vehicle having a linear stator

The levitating force of the levitation magnets of a magnetically levitated vehicle of the linear stator type is controlled for regulating the air gap width (S) between these levitation magnets (2) and a rail track having teeth of uniform, determined width in the travel direction. The control is responsive to the air gap width and, if desired, to the differentiation of the air gap width with respect to time. The control requirements are dependent on the vehicle speed, whereby in the low speed and stopping situations the primary task is a stabilizing one and in higher speed situations the primary task is a good following behavior. For this purpose a steering signal is derived from the output terminals of an induction conductor loop located in the surface of a pole piece of a levitation magnet facing the track teeth. The loop has a width corresponding to the tooth width. The frequency of the signal induced in the loop is directly proportional to the vehicle speed. The steering signal passes ...

Solenoid cassette pump with servo controlled volume detection

Servo controlled solenoids provide actuation of a pump piston and valves, and electronic LC resonance measurements to determine liquid volume and gas bubble volume. Third order nonlinear servo control is split into nested control loops: a fast nonlinear first-order inner loop causing flux to track a target by varying a voltage output, and a slower almost linear second-order outer loop causing magnetic gap to track a target by controlling the flux target or the inner loop. The inner loop uses efficient switching regulation, preferably based on controlled feedback instabilities, to control voltage output. The outer loop achieves damping and accurate convergence using proportional, time-integral, and time-derivative gain terms. The time-integral feedback may be based on measured and target solenoid drive currents, adjusting the magnetic gap for force balance at the target current.

Method for control of support gaps for a magnetic levitation vehicle and magnetic levitation vehicle with a control circuit operating with said method

A method and a magnetic levitation vehicle operating with said method are disclosed. The support gaps (10a, 10b), formed on operating the magnetic levitation vehicle, between a track (4) and a number of support magnets (6a, 6b) may be controlled by means of at least two support magnets (6a, 6b) in adjacent positions on a suspended frame (8) of the magnetic levitation vehicle, whereby the currents in the windings (16a, 16b) of the support magnets (6a, 6b) are regulated such that the support gaps (10a, 10b) have given set values (na, nb). According to the invention, when the currents through the windings (16a, 16b) are different under normal conditions, the set values (na, nb) for the support gaps (10a, 10b) are altered such that the current through the windings (16a or 16b) of the support magnet (6a or 6b) with the least current is increased and/or the current through the winding (16b or 16a) of a support magnet (6b or 6a) with the largest current is reduced.

The invention relates to a controller for a magnetic levitation vehicle, which determines switch-on variables for an actuator of a magnet according to a set of rules with reference to an air gap signal and a further sensor signal. In order to keep the magnetic levitation vehicle stable both when hovering and when travelling slowly and quickly, according to the invention it is proposed to use an additional filter circuit for the air gap signal, in which circuit a quantitative value for the air gap signal is formed. By comparing this signal with a response threshold derived from the set air gap signal, an adaptation signal can be obtained after rectification, which signal is dependent on the interference level of the system formed by the magnetic levitation vehicle and the travel path and on the speed of the magnetic levitation vehicle. Using this adaptation signal it is possible to intervene directly in the controller, for example to influence its corner frequency.
