A New Fuzzy PI Control Algorithm for Marine Electric Governor System

A new fuzzy PI control algorithm based on Z-N and critical proportion methods and the three-dimensional fuzzy rules is discussed. This kind of algorithm is designed by simplifying PI formula according to the Z-N and critical proportion methods and constructing a piece of fuzzy control table according to fuzzy control rules and fuzzy control reasoning. In real-time control, the PI parameter can be adjusted on line by looking up fuzzy control table. The simulation results of controlling the marine electric governor show that the algorithm raised in this paper has good performances.
