AbstractSwitched Reluctance Motors SRM have found domestics and industrial applications inrecent years because of their simple structure low cost ability to work in high speedmodes and quick developments in semiconductor technology SRM is very difficult tocontrol due to its very nonlinear characteristics There are also many uncertainties insystem parameters such as resistance inductance inertia and external load The controllerdesign of the SRM therefore is very challenging The purpose of this thesis is to use the new control method Back Stepping base onLyapunov method in designing a position controller and a nonlinear speed controller forSRM These controllers perform well in spite of variations and existence of uncertainties insystem parameters and they can cancel their effects via generating a suitable input to SRM In this thesis the structure and characteristics of SRM have scrutinized and analyzed Having an accurate model of motor the simulation and analysis of motor can beaccomplished better Therefore a new nonlinear model for SRM has been proposed thatenfolds saturation mode in the motor Then introducing Adaptive Nonlinear Back Stepping Control method and describing the systematic design two position and one speedcontrollers for SRM are proposed The proposed controllers are simulated in existence ofload uncertainty and saturation in the motor At the end a linear position controller and alinear speed controller are proposed for comparison Simulation results show goodperformance and reference signal tracking in spite of uncertainties
