Известен способ задани  напр жени  генератора привода бумагоделательной машины путем преобразовани  частоты задани  в напр жение .There is a known method of setting the voltage of a paper machine drive generator by converting the frequency of the setting into voltage.

Цель изобретени  - повысить точность и стабильность.The purpose of the invention is to improve accuracy and stability.

Достигаетс  это тем, что частоту задани  преобразуют в две с измененными фазами и подают на орган сравнени .This is achieved by the fact that the frequency of the task is converted into two with changed phases and fed to the organ of comparison.

На чертеже изображена блок-схема, при помощи которой осуществл етс  предлагаемый способ.The drawing shows a flowchart with which the proposed method is carried out.

Через логические элементы ИЛИ 1 частоту f подают на два одинаковых кольцевых делител  частоты 2. В каждом из делителей предварительно записаны разные числа. Величины их соответствуют номеру  чейки, в которой записана единица. При поступлении частоты f на входы делителей объема Л (где Л - число  чеек делител ) на их выходах будут существовать одинаковые частоты, равныеThrough logical elements OR 1, the frequency f is fed to two identical ring frequency dividers 2. Each of the dividers is pre-recorded with different numbers. Their values correspond to the number of the cell in which the unit is recorded. When the frequency f arrives at the inputs of the volume divider L (where L is the number of divider cells), the same frequencies will exist at their outputs, equal to

С выходов делителей частоты подают на триггер 3, в котором происходит преобразование фазового сдвига частот в пр моугольное напр жение соответствующей скважности. С триггера пр моугольное напр жение подают на фильтр 4, где выдел етс  посто нна  составл юща , котора  после дальнейщего усилени  по мощности  вл етс  сигналом задани  напр жени  генератора.From the outputs, the frequency dividers are applied to the trigger 3, in which the phase shift of the frequencies is converted into a square voltage of the corresponding duty cycle. From the trigger, the rectangular voltage is applied to the filter 4, where a constant component is extracted, which, after further amplification in power, is a signal for setting the voltage of the generator.

Измен   фазу, путем подачи одиночных импульсов на логические элементы / (на вход а или б в зависимости от желаемого результата ) , мен ют скважность, а следовательно, выходное напр жение U.Changing the phase, by applying single pulses to the logic elements / (to input a or b depending on the desired result), change the duty cycle, and therefore, the output voltage U.
