The proposed method is applied to modeling and simulating a certain marine diesel engine control system, which is a typical relay control circuit. Simulation results indicate that this circuit can be modeled and described by using the given colored Petri net with inhibitor arcs exactly. And the work procedures, input and output characteristics can be analyzed by simulating the corresponding Petri net model on Matlab platform. It is concluded that the research work presents an effective method in modeling and analyzing a relay control circuit, and the new method is highly practical.
