Control methods analysis of switched reluctance machine

The paper presents results of simulation studies of four-phase 8/6 Switched Reluc-tance Machine working in steady-state. Simulation model of the machine was de-veloped in Matlab/Simulink based on mathematical model. Simulation model was realized based on SimPowerSystems library, which contains for example models of semiconductor elements or power supplies. Controllable current sources and voltage measurement blocks were also used. Mathematical description of the ma-chine is difficult to obtain in nonlinear circuit simulation models. Nonlinear flux characteristics  (, i)  were obtained by field calculations and then were tabulated and used in circuit model of the machine. Studies were concerned the change of working point influence of motor on basic parameters especially on electromag-netic torque with various basic control methods (current control: soft-chopping and hard-chopping, voltage control: soft and hard, and one-pulse control). In current control was only used hysteresis regulator which held phase current at a certain level. Current control is possible to base speed, voltage control with its particular case called single-pulse control has wider use because it can be used above base speed, but for high-speed operation single-pulse control is used.
