Finite control set predictive torque control (FCS-PTC) has been widely studied in motor drive systems. FCS-PTC without weighting factor is the latest research trend in permanent magnet synchronous motor (PMSM) drives. This article proposed a new scheme based on a novel adaptive sliding-mode reaching law to eliminate the weight factors in the PTC method of PMSM. The proposed method enables the minimization of both torque ripple and flux ripple based on the elimination of the weighting factor. With the adaptive sliding-mode reaching law, the fasted tracking speed is maintained while sliding-mode chattering is suppressed. The simulation validation is carried out in MATLAB. The simulation results show that the method has better steady-state performance than one of the existing weightless factor schemes.

摘要

Finite control set predictive torque control (FCS-PTC) has been widely studied in motor drive systems. FCS-PTC without weighting factor is the latest research trend in permanent magnet synchronous motor (PMSM) drives. This article proposed a new scheme based on a novel adaptive sliding-mode reaching law to eliminate the weight factors in the PTC method of PMSM. The proposed method enables the minimization of both torque ripple and flux ripple based on the elimination of the weighting factor. With the adaptive sliding-mode reaching law, the fasted tracking speed is maintained while sliding-mode chattering is suppressed. The simulation validation is carried out in MATLAB. The simulation results show that the method has better steady-state performance than one of the existing weightless factor schemes.
