Abstract:The performances and lifespan of a marine main engine depend on the performances of its speed adjusting system to wide extent.To restrain load disturbance and enhance the reliability and control accuracy for the speed governor of the main engine,this paper designed a frequency conversion governor base on S7-200PLC and MM420 and converted the requirements for the performances of the whole system into the frequency transducing control.According to the characteristics of outer disturbances and speed adjusting process of the main engine,this paper added wave filtering function and step arithmetic to improve speed adjusting stability of the main engine.
Keywords:ship  main engine  digital governor  PLC  PID
