DOI: 10.1109/tie.2018.2877162
Abstract: The offset voltage variation of current sensors is mainly due to the thermal drift, and it causes torque ripples in current vector-controlled surface permanent magnet synchronous motor (SPMSM) drives. This paper proposes a current offset… read more here.

DOI: 10.1109/tits.2020.3023617
Abstract: In this study, we propose a robust nonlinear control method using the barrier Lyapunov function (BLF) under the lateral offset error constraint for lateral control of autonomous vehicles. Furthermore, for the application of the BLF-based… read more here.
