Automatic control of turn on position control of switched reluctance motor

This project consists of the implementation of Switched Reluctance Motor (SRM) in Matlab Simulation Software. This project presents the modelling, simulation and control aspect of the SRM. A new approach to the automatic control of the turn-on angle for the switched reluctance motor (SRM). Switched reluctance motor output can be varied simply by controlling the switching angles. Such control flexibility however tends to increase considerably the magnitude of the motor design tuning process. In attempting to reduce the amount of design calculation, it is very desirable to be able to define before the design process is started the rated operating condition of a switched reluctance drive in terms of set of switching angles. An approximately constant mean torque could be achieved if the same mean current value could be maintained during the rising inductance period. It is obviously desirable to minimize switching losses (during current chopping control) to maintain a constant mean torque with a minimum r.m.s phase current at different speeds. This condition may be achieved by adjusting the current switch-on advance angle as speed changes, in such away to maintain the current just before the occurrence of positive incremental inductance equal to the mean chopping current. A closed form turn on angle equation based on linear SRM model is introduced. The control of SRM is implemented in Matlab. Simulation result is found to be is accordance to theory.
