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 ... 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 ...
