To expand the description ability of Petri net, cooperation inhibit arc Petri net is introduced which can reflect the complex constraint relationship of multi-places to transition. The modelling example based on cooperation inhibit arc Petri net shows that the defined Petri net can describe the constraint relation of multi-places to transition accurately. To be convenient for system analysis and apply the cooperation inhibit arc Petri net in the modelling of turbocharged set, the cooperation inhibit arc Petri net based on hierarchical structure and the optimized control scheme are proposed. The results show that the proposed method can reflect the dynamic characteristics of turbocharged set precisely and improve the air/oil ratio without losing response time and economy which proves the validation of the proposed method.
