ABSTRACT: This technical report describes the design and implementation of an experimental system that can be used for the development and evaluation of speed sensorless vector control of an induction machine. The system is based on a single board controller which combines the computing power of a Texas Instrument 32-bit floating point TMS320C31 DSP with the peripherals needed to implement the vector control drive. Two sensorless vector control techniques have been chosen to be evaluated on the experimental system. The techniques are based on the rotor-flux based Model Reference Adaptive System (MRAS) and the back-emf based MRAS speed estimators. Practical issues related with the implementation of these two MRAS speed estimators have been investigated both in simulation and experimental environments, and the results are presented in this thesis.
