Description
цополнительно в пр мо пропорциональной зависимости от вычисленной разности.in addition, directly proportional to the calculated difference.
На чертеже приведена блок-схема системы автоматического регулировани , реализующей данный способ.The drawing shows a block diagram of an automatic control system implementing this method.
Система работает следующим образом. Изменение условий дроблени вызывает изменение как крупности дробленого продукта , так и концентрации материала в дробилке 1. Поскольку последн координата отклон етс на возмущение быстрее, сначала сигнал изменитс на выходе датчика концентрации 2, что приведет к по влению сигнала рассогласовани на выходе элемента сравнени 3, поступающего на вход регул тора 4 крупности. Последний вырабатывает управл ющие сигналы , поступающие через усилители 5 и б на. исполнительные элементы 7 и 8, которые начинают ликвидировать по вившеес отклонение от заданного значени концентрации материала в дробилке и, следовательно , уменьщить по виБщеес отклонение завис щей от концентрации крупности продукта дроблени . По истечении времени запаздывани начнет измен тьс сигнал на выходе Датчика 9 крупности, что приведет к по влению на выходе элемента сравнени 1О сигнала рассогласовани . Это, в свою очередь, вызовет дополнительное изменение управл ющих сигналов до тех пор, пока не будет стабилизирована на заданном уровне крупность продукта , задаваема задатчиком 11 крупности .The system works as follows. A change in the crushing conditions causes a change in both the size of the crushed product and the concentration of the material in crusher 1. Since the last coordinate deviates perturbation faster, the signal will first change at the output of the concentration sensor 2, which will cause the error signal to appear at the output of the comparison element 3 to the input of the controller 4 size. The latter generates control signals through the amplifiers 5 and b on. actuators 7 and 8, which begin to eliminate the increasing deviation from the set value of the material concentration in the crusher and, consequently, reduce the most significant deviation depending on the concentration of the size of the crushed product. After the lag time has elapsed, the signal at the output of the Sample 9 will begin to change, which will result in the output of the error signal 1O at the output of the comparison element. This, in turn, will cause an additional change in the control signals until the size of the product is stabilized at a given level, specified by the size setting unit 11.
