Control of Switched Reluctance Motor Containing a Linear Model

The principle of operation of the switched reluctance motor (SRM) drive demands that the motor and converter be treated as one unit. The control of the SRM is very important and difficult. The motor´s double salient structure makes its magnetic characteristics highly nonlinear. The motor flux linkage appears to be a nonlinear function of stator currents as well as rotor position. This paper deals with control parameters and converter topology of switched reluctance motor, where an equivalent circuit model is used. Its converter topology and its control are discussed in detail. Control parameters and its converter topology are obtained by using linear model and dynamics of the switched reluctance motor. Simulation studies are performed for phase currents and the steady-state motor operation
