The main objective of this thesis is to build and test a SRM drive system to provide a research platform for having more investigations in this field. First, a literature study of switched reluctance motors which includes fundamental operation, control techniques and energizing methods is done and second, a linear magnetic mathematical model is developed in Matlab / Simulink to analysis the dynamic response of the machine using a PI speed controller and a feedback control system under different working conditions. A voltage source strategy is applied to the SRM and since each phase is controlled by pulses of current during the torque production with a repeating sequence, it is important to calculate the turning on, on  , and off, off  , angles properly. In addition, a hysteresis current controller is required to maintain the current within a preset band. To operate the SRM , an experimental setup and an assembly of PCB are needed. These boards are the main part of the project and they are controlled by a dSPACE system. Simultaneously, protection and measurement units are used to monitor SRM drive in faulty situations. Finally, an open loop control is implemented in a real time environment and practical results are compared with theories to obtain a good assessment of the system.
