Due to the new generation DSP (Digital Signal Processor) has the characteristics of the fast computation (150MIPS) and the complete peripheral circuits for motor drive, therefore a fully digital controller of PMSM drives system, which includes current vector control scheme, SVPWM generation, A/D conversion, coordinate transformation, QEP detection and an intelligent strategy, can be integrated and realized by software within a DSP chip. For increasing the performances of PMSM drives, an adaptive fuzzy controller constructed by fuzzy basis function and a parameter adjustable mechanism is proposed and applied in position control loop to cope with the system uncertainty and to increase a fast tracking response. To confirm the effectiveness of the proposed system, an experimental system included by a PMSM, DSP control board, inverters, rectifier have been set up and some experimental results have been validated the theoretical ones.
