Abstract
Controlling the temperature of the evaporation chamber to maintain stability is the key to the normal operation of the tryptophan evaporation process.In this paper, the basic principles of Dahlin control algorithm are analyzed and studied, the S7-300 PLC system control program based on Dahlin algorithm is designed and written, and the control effect of Dahlin and conventional PID is analyzed by simulation.The results show that compared with the conventional PID controller, the Dahlin control algorithm converges faster and the overshoot is smaller, and the control program has certain engineering application and promotion value.
