Description
При изменении настройки аппаратуры 1 на ее выходе измен етс расход топлива. Это изменение расхода топлива приводит к изменению сигнала на выходе датчика 2, поступающего на элемент 3 сравнени . В элементе сравнени сопоставл ютс сигнал фактического расхода топлива с выхода датчика расхода и сигнал потребного расхода, заложенного в нелинейном блоке 4 в зависимости от частоты вращени привода. Разность указанных сигналов поступает в интегрирующий блок 5 и далее на след щий привод 6, который выводит испытуемую аппаратуру на заданный режим . Донолнительный датчик числа оборотов 7 вырабатывает сигнал, пропорциональный частоте вращени привода, поступающий в нелинейный блок.When changing the setting of the apparatus 1 at its output, the fuel consumption changes. This change in fuel consumption leads to a change in the signal at the output of the sensor 2 fed to the reference element 3. In the comparison element, the signal of the actual fuel consumption from the output of the flow sensor and the signal of the required flow rate embedded in the nonlinear block 4 are correlated with the rotation frequency of the drive. The difference of these signals goes to the integrating unit 5 and further to the next drive 6, which brings the tested equipment to the specified mode. A further speed sensor 7 produces a signal proportional to the frequency of rotation of the drive, which enters the non-linear unit.
Таким образом, в стенде внутренней отрицательной обратной св зью охвачены не только интегрирующий блок, но и след щий привод , в результате чего повышаетс стабильность характеристик стенда, точность испытаний .Thus, in the stand, internal negative feedback covers not only the integrating unit, but also the follower drive, as a result of which the stability of the characteristics of the stand and the accuracy of the tests are increased.
