Claims (4)

1. Способ позиционного контроля вращающегося элемента, удерживаемого постоянным магнитным полем, посредством определения позиции этого элемента с помощью сенсорного анализа положения и использования дополнительных управляющих катушек, влияющих на магнитное поле постоянной магнитной подвески и пропускающих электрический ток, сила которого зависит от позиции данного элемента, отличающийся тем, что силу тока, проходящего через управляющую катушку, подвергают широтно-импульсной модуляции согласно требуемому значению, зафиксированному в корректоре, установленном после сенсорного устройства позиционирования, в котором для достижения требуемой силы тока напряжение повышают, при этом текущие показания позиционного сенсора сохраняют в течение определенного временного интервала, начиная, соответственно, с фронта импульса управляющего тока, а сенсорное позиционирование на это время приостанавливают.1. The method of positional control of a rotating element held by a constant magnetic field by determining the position of this element using sensory analysis of the position and the use of additional control coils that affect the magnetic field of a constant magnetic suspension and transmit an electric current, the strength of which depends on the position of this element, different the fact that the strength of the current passing through the control coil is subjected to pulse width modulation according to the required value recorded in the corrector installed after the touch positioning device, in which the voltage is increased to achieve the required current strength, while the current position sensor readings are stored for a certain time interval, starting, respectively, from the front of the control current pulse, and touch positioning is stopped for this time. 2. Способ по п.1, отличающийся тем, что текущие показания позиционного сенсора в бесколлекторном синхронном электродвигателе, касающиеся возбуждающих импульсов обмоток, временно сохраняют в течение определенного интервала, начиная, самое позднее, с фронта импульса возбуждающих импульсов, при этом сенсорное позиционирование на это время приостанавливают.2. The method according to claim 1, characterized in that the current readings of the position sensor in the brushless synchronous electric motor relating to the exciting pulses of the windings are temporarily stored for a certain interval, starting at the latest from the pulse front of the exciting pulses, with touch positioning on it time pause. 3. Способ по п.1 или 2, отличающийся тем, что требуемое значение показаний корректора, подключенного последовательно за устройством сенсорного позиционирования, возводят в квадрат и через интервал, равный усредненному времени достижения порогового перерегулирования этого значения, позиционную коррекцию приостанавливают до последующего порогового провала.3. The method according to claim 1 or 2, characterized in that the required value of the readings of the corrector connected in series after the touch positioning device is squared and after an interval equal to the average time to reach the threshold overshoot of this value, the positional correction is stopped until the next threshold failure. 4. Способ по пп.1, 2 или 3, отличающийся тем, что в корректоре, подключенном последовательно за устройством сенсорного позиционирования, используют PID-корректор с I2-компонентом.4. The method according to claims 1, 2 or 3, characterized in that in the corrector connected in series with the touch positioning device, a PID corrector with an I 2 component is used.
