With respect to the automatic drilling control of geological winch motor, the paper proposes a novel control method based on fuzzy theory for winch motor drive. The paper analyzes the operation principle of automatic drilling systems. It designs a novel winch motor drive system based on a Permanent Magnet Motor (PMM). The paper proposes an intelligent fuzzy logic algorithm that could be applied to the winch motor automatic drilling system in order to replace the traditional PID control algorithm. The system based on fuzzy logic settles the conundrum of the instability of winch motor drilling pressure caused by time-delay, time-variability and nonlinearity of controlled objects. The results prove fuzzy logic can pledge the stability of the winch motor drilling pressure, and the drilling system is efficient in operating. The research is beneficial to geological winch motor automatic drilling control both in theory and in technology.
