Abstract
This paper proposes a straightforward second-order sliding mode control (SMC) approach to minimize current distortions and torque ripples of a switched reluctance motor (SRM). In the first step, conventional SMC is briefly recalled and detailed. Then, a special attention is paid to the synthesis and the implementation of a second-order (SM2) approach. Stability analysis of these two approaches is ensured. It will be shown that the proposed second-order SM approach offers a lower harmonic distortion of the motor currents, a reduction of the torque ripples, and the elimination of chattering phenomena. The effectiveness of the proposed SM2 is verified by simulation results then validated by experiments.

Imen Bahri
Imen Bahri received the Engineer degree in 2007 from the national engineering school of Tunis and the Ph. D degree in electrical engineering from the University of Cergy-Pontoise in 2011. She is currently working as an Assistant Professor of electrical and computer engineering at the University of Paris-Sud since September 2012. She is also join the GeePs (Group of Electrical Engineering of Paris) laboratory. His current research interests include the control of electrical machines and drives, vibration reduction control strategies, efficiency improvement, sensorless control strategies, real-time FPGA-based implementation of controllers and software/hardware partitionning solutions.
Hana Maamri
Hana Maamri was born in Sfax, Tunisia in 1989. She obtained at the national engineering school of Sfax (ENIS) in 2014 the electrical engineering diploma after an internship at the electrical engineering laboratory of Paris (Lgep) with a subject around the development of a multiphysical analytical model of a variable reluctance motor fitted to an electric car. In 2015 she obtained a master's degree in energy engineering physics at ENS Cachan Paris Sud and SUPELEC. One year after, she started her professional experience at Renault as a resilumation leader on advanced emergency breaking system AEB and as a system validation leader in 2019. This expertise in driving assistance systems with Renault is an asset in the automotive field career allows Hana until today to be the engineering leader on the software and algorithms fusion team. Her research interests include electric power components and systems.
