The FPGA controller for switched reluctance drives investigation

The paper presents a topology of fast switched reluctance motor (SRM) controller, designed for measure parameters of drives, witch based on new supply systems designed for these type of the motors. To reduce an algorithm realization time and delay of output signals in respect to rotor position angle given from encoder, the control system is based on FPGA device. External circuits were connected using current loops to limit the noise of control signals. The system was equipped with voltage and current sensors, used in the control process, which enables simultaneous recording of measuring waveforms. Implemented USB interface allows to save measurement results on a computer.
