dc.description.resumoThis thesis presents contributions in the field of advanced control strategies for SRMs. These techniques seek to improve the performance of SRMs, specially regarding torque ripple minimization, aiming to mitigate a known drawback of the machine. Firstly, a SRM firing angle optimization procedure based on the particle swarm optimization algorithm is proposed. The procedure is intended for SRMs operating in the current controlled region, below base speed, and seeks a balance between energy efficiency and reduced torque ripple. As a second contribution, a discrete-time super-twisting sliding mode current control scheme for switched reluctance motors is proposed. The proposed method presents enhanced current tracking capabilities, enabling lower torque ripple in SRM drives operating with TSF strategies. The strategy ensures a fixed switching frequency due to PWM implementation and presents a novel gain design procedure, using a cost function. This enables a systematic and straightforward way to determine the controller gains. The procedure is repeated for different speed values, allowing for a variable gain structure, where the controller gains are adjusted online based on the rotor speed. Simulation and experimental results are provided in order to demonstrate the effectiveness of the proposed control schemes.por
