Characterize a nonlinear machine
The source describes a 6/4, 2 kW switched reluctance generator delivered without detailed electromagnetic information. Its strongly nonlinear characteristics were a central difficulty for the control model.
Measure across rotor position
Locked-rotor testing with AC excitation covered aligned through unaligned rotor positions to identify nonlinear flux-linkage behavior. The source connects this characterization with back-EMF, torque and phase turn-on/turn-off considerations.
Model the phases and add feed-forward
The project used MATLAB/Simulink to examine sequential phase excitation, then deployed the algorithm to a dSPACE prototype controller. Estimated back-EMF was fed forward in real time to address current overshoot associated with the machine’s nonlinearity.
Reported DC generation
The document reports DC power extraction and describes the overshoot-control approach, with a supplied demonstration video. It does not quantify the extracted power, residual overshoot or performance across an operating envelope.
