... Finn and was designed to control a brush-less DC motor. However, by
constructing a feedback loop that can detect the outputs of an induction motor, we
can use this motor controller to control an ... Design
3.1. The basic control format
In essence, we are endeavoring to design a controller that can vary the torque induced in
the rotor of the motor. To do this, the induction motor controller ... drawn by the
induction motor form the feedback portion of the design. Hence, the major aim of this
thesis project is to develop a control strategy for the DSP controller that controls the
