Abstract: This work presents two control strategies, with the objective of reducing the undesirable effects of ripple and dead zone in the speed response of a switched reluctance motor (SRM) 8/6. The first strategy aims to reduce the dead zone by applying a double integrator classical controller, while the second strategy proposes a new strategy to reduce the speed ripple, which works in conjunction with a classic PI controller. The strategy, based on digital simulations shows a reduction on the dead zone effect and speed ripple, the simulations were performed using the Matlab® / Simulink software and are based on a simplified non-linear model that has the non-linearity of Coulomb friction plus viscous friction, as well as an ideal inverter circuit.
