Abstract:
According to the I/O data of the annealing processes of a box annealer, a linear dynamic
model is set up using identification methods. Based on the optimal control theory, the energy
saving control rule, the on-off switching manner, is derived. With the consideration of physical
characteristics of the annealer, the peak value prediction method is presented to determine
the optimal control. Through digital simulation, satisfactory results have been obtained with
over 5% of the energy saved.
