The Permanent Magnet (PM) Synchronous Motor is ideal in the field of the low power high performance servo, since it is controllable and its vigorous performance is excellent. However, the variations of moment inertia, load torque, and motor internal parameters have been a major difficulty to deal with speed control. This paper investigates the fuzzy logic controller based speed control for a vector-controlled PM synchronous motor drive. The fuzzy logic is based on the speed error and change of speed error measured between the actual motor speed and the reference speed. The robust control performance of the fuzzy logic controller is evaluated for various operating conditions using the parameters of a prototype PM synchronous motor and compared to that of conventional PI controller. The design and application of the fuzzy logic controller are considered and discussed.
