IDENTIFICATION OF FLUX CHARACTERISTIC OF SWITCHED RELUCTANCE MOTOR WITH THE INFLUENCE OF MUTUAL INDUCTANCE AND MAGNETIC SATURATION

Abstract

The switched reluctance motor has many advantages such as simple construction, large starting
moment, and capable of being used in systems requiring high speed. However, the disadvantage of
this motor is that the ripple torque is large and difficult to control. In order to apply the control
methods, the motor's mathematical model needs to be precisely defined. Unlike conventional
motors, the mathematical model of the switched reluctance motor requires knowing the flux
characteristic, which can only be accurately determined based on experimental measurements. The
experimental measurement process requires a real equipment system, complicated installation
process, not suitable in research, design, and simulation of control algorithms. To solve this problem,
the paper proposes a mathematical function of the magnetization characteristic, using a neural
algorithm to check the accuracy of the proposed function. The magnetization characteristic function
for the switched reluctance motor is built considering the influence of mutual inductance phases and
magnetic saturation, magnetization function is used in the development and evaluation of control
algorithms for switched reluctance motor.
