This dissertation proposes the design and implementation of a novel switc
hed reluctance drive system. First, the structure, basic principles, and model
of the switched reluctance motor are described. Next, a high performance conv
erter is designed which can improve the driving ability of the excitation curr
ent by boosting the bus voltage during phase commutation. In addition, a progr
ammable current command, which is related to the self inductance and can effec
tively reduce the torque pulsation, is proposed Then, a hybrid controller is p
roposed to obtain the better speed response and load disturbance response than
traditional PI or sliding mode controller. After that, a new sensorless techn
ique that can easily estimate the shaft angle by measuring and shaping the ind
uced voltage is developed. A closed loop drive system is achieved by using the
proposed sensorless technique. Finally, several experimental results are show
n to validate the theoretical analysis. This dissertation provides a new direc
tion of designin a switched reluctance drive system.
