Two-stage workflow control with a predictive component

Background. Despite the wide use of controllers with proportional-integral-differential control law (PID controllers), the issue of expanding the limited functionality of not taking into account the trend of changing technological parameters is open. Methods. The control action is formed taking into account the predicted value of the technological parameter. Verification. The proposed method is verified for the reactor that processes the waste gases in sulfur production. Conclusions. Using a PID controller with a predictive component significantly improves the quality of control, reduces the maximum deviations of process parameters from specified values, contributing to additional energy saving and a significant increase in the efficiency of automated process units in the oil and gas industry and mechanical engineering.
