Super-twisting control design of speed regulation and tracking for a surface-mounted PMSM

Abstract

This work is devoted to presenting a second-order sliding mode control for speed regulation and tracking for a surface-mounted permanent magnet synchronous motor. We tune the conventional PI controllers using the field-oriented control scheme. On the other hand, we design a generalized super-twisting sliding mode control, improving the performance characteristics when the machine is under the effects of external torque. Finally, a high-precision emulator is used to validate the theoretical results.
