RT-LAB Simulator Platform for Simulation of Switched Reluctance Machine

RT-LAB simulator platform for simulation of switched reluctance machine is described in the paper. Basic circuit block of OP5311 digital input, basic circuit block of OP5312 digital output and the photograph of voltage convert circuit are given. The hardware synchronized simulation models are setup includes period calculation of rotor position pulse signals in phase a, the simulation models of launching subsystem, start-subsystem of SRM system hardware synchronized simulation, the simulation models of RT-LAB digital input & output system and simulation models of RT-LAB analog input system. According to the three-phase 12/8 structure Switched Reluctance machine system, the Semi-physical simulation experiments is carried out depending on the established hardware synchronization simulation model using RT-LAB. The rotor speed response curve measured by the oscilloscope of SC subsystem, the measured phase current waveforms while the machine is at three different given rotor speed under the steady-state operation and the speed rotor response curves of sudden load increasing and sudden load shedding are also given.
