Switched Reluctance Machine Control Strategies for Automotive Applications

This paper analyzes hysteresis (HCR), delta modulation (DCR), and pulse width modulation (PWMCR) current regulators for switched reluctance machines. The current regulators are implemented in real-time for a 6/4 3-phase 15 kW switched reluctance machine (SRM). The comparative study of the performance of the current regulator is focused on the current transient response, deviation from the current reference, acoustic noise, and vibration for soft chopping and hard chopping mode of operation.
