For the forecast method, wavelet transform is used for preprocessing, and grey model GM（1,1） for forecasting. The performance of the wavelet-based GM（1,1） （WGM（1,1）） is illustrated through field data based load characteristic prediction and analysis. A cutterhead mode control strategy （CMCS） is presented based on the WGM（1,1）. The CMCS can not only provide operators with some useful operating information but also optimize the stator winding connec-tion. Finally, the CMCS is tested on a cutterhead driving experimental platform. Results show that the optimized stator winding connection can improve the system efficiency through reducing the energy consumption under part-load conditions. Therefore, the energy-saving CMCS is useful and practical.
