Resumo
This work presents modeling, driving and speed control techniques for the switched reluctance
motor. The objective is to improve the computational model, the control response and the
machine efficiency. A parametric regression model was used to find the inductance profile of
the switched reluctance motor and from the new inductance profile model. The drive and
control techniques are shown: i) with classical speed control acting on the excitation voltage
and fixed switching angles, ii) with classical speed control acting on the switching angles and
fixed excitation voltage and iii) with classical speed control acting on the excitation voltage, in
this case, with dynamic switching angles and controller parameters. The inductance profile is
represented analytically and inserted into the machine computer model, allowing greater
precision and low computational cost. The speed controls acting on the excitation voltage with
dynamic controller parameters and dynamic switching angles allowed shorter response time
for a wide range of control, higher efficiency, low computational cost and simplified
implementation and maintenance. The techniques proposed in this work obtained precision of
the computational model with respect to the system (in workbench) and optimized
parameters in a wide range of the speed control, allowing an improvement of switched
reluctance motor efficiency.
