Description
логового вычислительного устройства 8 пропорционален температуре материала на выходе из теплообменника. Этот сигнал поступает на самопишущий прибор 9 и в качестве переменной величины на регул тор 10, заданием которого вл етс выходной сигнал регул тора 11 обратной св зи. Выходной сигнал основного регул тора 10 поступает на исполнительный механизм 12, измен ющий подлчу греющего агента в теплообменник 1, и тем самым компенсирует то или иное возмущение. Таким образом осуществл етс комбинированна система регулировани . Основные возмущени компенсируютс практически сразу, без запаздывани схемой регулировани по возмущению с использованием аналогового вычислительного устройства 8.The log computing device 8 is proportional to the temperature of the material exiting the heat exchanger. This signal is fed to the recorder 9 and, as a variable, to the controller 10, whose setting is the output signal of the feedback controller 11. The output signal of the main regulator 10 is fed to the actuator 12, which changes the supply of the heating agent to the heat exchanger 1, and thereby compensates for one or another disturbance. Thus, a combined control system is implemented. The main disturbances are compensated almost immediately, without delay by the disturbance control circuit using an analog computing device 8.
Дл уменьшени возможной статической ошибки регулироваии по возмущению и учета неконтролируемых возмущений введен контур обратной св зи, позвол ющий корректировать работу основного регул тора 10 по фактической температуре материала на выходе из теплообменника 1.In order to reduce the possible static error in the perturbation control and to take into account uncontrolled perturbations, a feedback loop was introduced, which allows to correct the operation of the main regulator 10 according to the actual temperature of the material at the outlet of the heat exchanger 1.
Таким образом, предлагаемый способ позвол ет поддерживать температуру исходногоThus, the proposed method allows to maintain the temperature of the initial
материала на выходе из теплообменника на посто нном уровне с учетом всех определ ющих процесс теплообмена технологических параметров. При этом достигаетс минимально необходимый расход греющего агента дл конкретных условий работы аппарата.material at the outlet of the heat exchanger at a constant level, taking into account all technological parameters that determine the process of heat exchange. In this case, the minimum required consumption of the heating agent is achieved for specific operating conditions of the apparatus.
