Analytical equations can be used to model the electrical characteristic
of a SR motor. The model is then utilised to find an optimum phase current that
produces smooth torque operation. The optimum phase current can be generated
based on an explicit torque profile applied to each phase of the SR motor. The
sum of all the explicit torque profiles produces a constant value and thus a
constant or smooth torque operation of the SR motor. Alternately, the optimum
phase current can be generated based on a total reference torque without defining
an explicit torque profile for each phase of the SR motor. As a result, an implicit
torque profile is produced in each phase of the SR motor corresponding to the
total reference in order to ensure a constant or smooth torque operation.
