This paper presents a control scheme for smooth torque production in permanent-magnet synchronous motor drives. The proposed control scheme consists of two techniques: a feedforward compensation for torque ripple minimization and an online parameter estimation technique for harmonic fluxes. The feedforward compensation is constructed on a position-sensorless vector control system and generates voltage commands to suppress torque ripples. The command calculation process requires the parameters of the harmonic fluxes; therefore, the proposed control scheme includes their estimator and calculates them from detected current information. These techniques are simpler than existing ones and can be implemented on a computational device with a small amount of calculation load. The proposed control scheme is verified by performing simulations and experiments.

We propose a new beatless control mechanism for permanent-magnet synchronous motor (PMSM) drives. In drive systems, the three-phase voltage source induces a ripple component whose frequency is six times that of the voltage source frequency in the DC voltage. Therefore, if the motor frequency becomes six times the voltage frequency, a beat phenomenon, which causes an increase in the motor current ripple is observed. We analyze the beat phenomenon which causes current ripples and propose a method based on periodic disturbance current regulation, i.e., beatless control. We carry out time-domain simulation and various experiments and demonstrate the effectiveness of the proposed controller.
