Using Hybrid Petri Nets (HPNs) together with a continuous mathematical model, a combined modeling method for continuous‐process dynamic scheduling and supervisory control is presented. This method can describe both continuous characteristics of a continuous process and its discrete control strategies on the same level. An ideal binary mixture distillation column is used as an example to illustrate the proposed method. Based on the combined model, a supervisory control scheme is also provided.
