Ingenious digital controller for switched reluctance motor using Verilog (HDL)

This paper presents an advanced method of position estimation and PWM generation for a switched reluctance motor (SRM) using Verilog. SRM cannot be run directly from the mains and requires a power converter and amicable controller, which must be integrated with the motor. The conventional controllers occupy more space and consume more energy. In this paper, Verilog has been used for the rotor position estimation and PWM generation to control a 3 phase 6/4 pole switched reluctance motor. With this method it is possible to save a considerable amount of energy as well as space in the controller circuits since all the control algorithms are implemented using a single chip. Both voltage and current control techniques are discussed.
