FPGA-based control of output voltage of SRG drive system

The paper presents an FPGA-based output voltage control system of a fourphase switched reluctance generator above base speed. The presented control strategy uses a digital PI controller to vary turn-off angle at fixed turn-on angle under single-pulse mode. Simulation tests were conducted based on the simulation model built in the Matlab/Simulink environment. The results of the simulation and laboratory tests as waveforms of voltages and currents are presented. Based on the presented control system, the dependencies of overall efficiency in the function of turn-on angle and ratio of output power to rms phase current (Pout av=Iph rms) in the function of turn-on angle were determined. They allow for the selection of a proper value of turn-on angle for the optimal performance of the generator during the output voltage control. The results obtained from laboratory and simulation tests are discussed in the conclusions.
