Charge and discharge control of a switched reluctance motor based flywheel

doi:10.12028/j.issn.2095-4239.2018.0156

Abstract

Abstract: A mathematical model was developed for a flywheel system based on the characteristics of a switched reluctance motor (SRM) and simulated under a Matlab/Simulink environment. The influence of the maximum permissible current and the breaking angle on the system performance was analyzed. Based on the analyses, a control mode of charging and discharging of the system was designed. During charging, the current chopper control and angle position control were adopted; whereas in discharging, the current chopper control was adopted. The simulation results showed that the charging and discharging processes had the characteristics of a fast response speed and a high steady state precision with the proposed control method. Finally, the feasibility of using SRM based flywheel as an uninterruptible power supply was verified by simulation.
