Abstract :
In this paper the problem of effective current control in Switched Reluctance Machine (SRM) drives is addressed. A sliding mode pulse width modulator (SMPWM) is introduced to govern the inherently highly nonlinear system dynamics. The proposed SRM drive is analyzed theoretically and subsequently validated through simulation. Satisfactory dynamic performance and precise speed control with reduced torque ripple, uniform power electronic device utilization, and approximately constant switching frequency is obtained. The feasibility of the above control scheme is validated by experimental measurements on a prototype 6/4 SRM drive.
