Feedbacks signals of rotor speed and motor torque are essential in most of switched reluctance (SR) motor control applications. An SR motor has highly nonlinear characteristics that do not allow to be modeled by simple equations. Hence, the feedback signals can not be mathematically calculated from the model. Instead of calculation, they should be measured or estimated. In direct torque control (DTC)...
Switched reluctance (SR) motors are expected as low-cost variable-speed motors in industry applications. However, large torque ripple from magnetic saliency constructions is one of serious problems. Strong nonlinearity of magnetic operating area makes the analysis as well as control much difficult. In the paper, we propose a novel torque control method based on the idea of direct neighboring phase...
We propose a novel drive circuit for switched reluctance (SR) motors, which can be constructed using general 3-phase power modules without external inductors or devices. This drive method has several advantages including low cost, high efficiency, and compactness. It is simulated on SPICE, including the controller, and some control algorithms and the driving performances have been investigated. Then,...
