Untimely parts supply will restrict readiness rate of carrier aircraft. The transporting time and supply disturbance are the main uncertain factors in the parts supply system of carrier aircraft. Considering nonlinearity and uncertainty in the parts supply system of carrier aircraft, a fuzzy system for the parts supply is established using fuzzy rules of production and transportation strategy. A robust control strategy is designed based on overlapping fuzzy partition. The data of "Nimiz" aircraft carrier are used in simulation. A comparison with the conventional robust control strategy illustrates that the proposed method can reduce the fluctuations of parts quantity and the total cost induced by supply disturbance and supply transporting time. Moreover, the robust stability of fuzzy parts supply system can be ensured, and the carrier aircraft parts can be supplied in time at a certain cost. Simulation also illustrates the usefulness and quickness of the improved robust control method based on the fuzzy system.
