| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 96 === The object of this thesis is to realize the speed control of permanent magnetic synchronous machine (PMSM) using the self-tuning fuzzy technique. The control of state variables uses three phase mathematical transformation model to decouple abc states into q-axis and d-axis variables in synchronous rotating frame for field oriented control (FOC).
Following that, we implement the algorithms of FOC, space vector pulse-width modulation (SVPWM), and speed control using the digital signal processor (DSP). Regarding to the influence of controller parameters on dynamic response of the motor speed, this thesis proposes the speed control of PMSM using self-tuning fuzzy technique. By the self-tuning technique, the on-line fuzzy logic controller (FLC) output can give better speed response under the load disturbances or variable speed commands.
Testing results show the proposed control strategy is more robust than the traditional proportional-integral control.
