Abstract:  Traditional PID control system can not self-adjust its parameters with external conditions and has low control accuracy and bad robustness. To solve these problems, in this paper the fuzzy adaptive PID control system was applied into BLDCM. The parameters self-tuning online by employing fuzzy control principle were introduced. The simulation and experimental results show that the fuzzy control system has faster dynamic response, higher precision, better robustness and smaller over-shoot.
