Abstract A novel direct self control (DSC) strategy of 30-angular flux trace based on double fold corner modulation is proposed in this paper, which reduce all low dominating harmonics of the stator current and flux. This is achieved by increasing the stator flux corner and choose appropriate flux trajectory. The theoretical and experimental results show that the proposed method retains the advantages of concise in classic DSC and further reduce the dominating distortion in comparison to 18-corner DSC and improves the control performance.

Key words： Direct self control double fold corner stator flux trajectory low harmonics theoretical and experimental
