Design and Implementation of a Three-Phase Induction Motor Control Scheme
... 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 torque...
