In this mode, the control instrument outputs two control adjustment quantities, one to adjust the speed of the feeding device and the other to adjust the speed of the belt scale itself. In this way, the amount of materials delivered is uniform, the measurement accuracy and control accuracy are very high, and the system is reliable, but the mechanism is complicated, the investment is large, and the control model is difficult to determine.
In actual application, the choice of speed-adjusting batching method should be determined according to factors such as measurement accuracy, control accuracy, system reliability, investment, and occupied space of the user.
