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 ... TMS320F243 DSP controller. This is manufactured by the Texas Instruments
Company and is one of the major components on David Finn’s motor controller.
For this thesis project, a softwarecontrol design...
