Abstract: After analyzing the vacuum casting process, velocity control of mixing motor and injecting motor were key factors which affected product quality. To control velocity of drive motors precisely, intelligent prediction controller based on Fuzzy Wavelet Network (FWN) was proposed, which was combined with intelligent control and predictive control. Permanent Magnet Synchronous Motor (PMSM) acted as control object and rotor velocity acted as control target. The FWN solved modeling accuracy problem. Algorithm implementation process was described in detail. Finally, simulation experiments showed the intelligent prediction controller was with better robustness, rapid tracking and stability.
