This system framework contains sensor-less direct field oriented control of 3-phase induction motor. The motor speed is controlled by using estimated speed as the speed feedback from the speed estimator of induction motor. The control strategy can be evaluated on eZdsp2812 board with power inverter and real induction motor. The system consisting of digital motor control modules is gradually built up until the speed control loop is finally closed. The incremental builds are included in the software to confidently build up the system. The software for this system and associated modules are developed using IQmath arithmetic.

The GLOBAL_Q setting (found in IQmathLib.h) allows one to rapidly adjust the overall Q number for the whole system. Thus, the "IQ" system can be easily evaluated in terms of overall resolution, dynamic range, or quantization problem.

Note: C28x DMC library must be downloaded to execute this motor control system.
