This paper develops a novel switching variable proportional desaturation proportional integral (SVPDPI) regulator for speed control of switched reluctance motor (SRM) drive system. Firstly. the idea of desaturation is adopted in the SRM drive system in order to eliminate the integral saturation phenomenon of traditional proportional integral (PI) regulator. Secondly. https://www.roneverhart.com/Tc-Electronics-M350-Multi-Effects-and-Reverb-Processor-M350-p36058/
