The disc coreless permanent magnet synchronous motor (DCPMSM) is drived by an inverter with current source chopper. A fast global terminal sliding mode control (FGTSMC) method is proposed in this paper for the torque loop, and the instantaneous torque is predicted. The proposed control system can dramatically reduce the current ripple of the DCPMSM by low inductance. The feasibility of this proposed...
The disc coreless permanent magnet synchronous motor has several advantages, such as strong overload capacity, zero cogging torque, sinusoidal back EMF, and linear parameters. The motors tend to have low inductance because of the coreless structure. There is a stringent current ripple in the motor winding that produces unacceptable torque ripple if driven from conventional drivers with a pulse width...
