Optimizing Performance in Current-Controlled Switched Reluctance Generators

Switched Reluctance Generator - Modeling, Design, Simulation, Analysis and Control a Comprehensive Review

“…With optimal excitation angles (turn-on and conduction angles) maximization of efficiency by minimizing the losses was carried out in [63]. A problem of optimal efficiency in single pulse controlled SRG drive operating on a wide speed range is investigated in [64][65][66] and a controller that online determines the optimal turn-on and turn-off angles is proposed for providing high efficiency and low torque ripple and a smooth transition between PWM control mode to single pulse control mode is achieved in [66].…”

High Efficiency Operation of a Switched Reluctance Generator over a Wide Speed Range

“…The turn-on/off angles are defined as control variables, the turn-on angle is set based on the output power, and the off angle is selected to achieve optimal efficiency under each power level and speed. Current chopping and single pulse control are adopted as an inner loop to retain the DC-link voltage in [10] and [11], respectively. Moreover, an optimal turn-on/off angle is chosen by an analysis of the system efficiency and torque ripple in [10].…”

Moreover, an optimal turn-on/off angle is chosen by an analysis of the system efficiency and torque ripple in [10]. While this occurs, the optimal turn-on/off angles are calculated by the ratio of two fluxes in [11].…”

Switched Reluctance Generator Output Voltage Ripple Reduction Based on Fuzzy Sliding Mode

“…At present, the researches of domestic and foreign scholars on SRG output voltage ripple reduction are mainly as follows: the optimization design on main power circuit and structure parameters of SRG, the control strategy based on current distribution function [5] and the introduction of intelligent control algorithm to design a feedback controller for optimization [6][7][8] . In Document [4] , the output voltage is conducted optimization control through the design of capacitor filter and voltage feedback regulator, but effects of some harsh conditions on SRG output voltage are not taken into account, and the change of power circuit is bound to bring a certain project difficulty for update and promotion of SRG.…”
