Abstract: This thesis work deals with sensor-less speed control of induction motor in its entire speed range. Flux linkage and rotor speed estimators are designed, simulated and implemented on 180W induction motor using Texas Instrument DSP board TMDSHVMTRPFCKIT. Estimated flux-linkage has been used as reference for direct field oriented control of the machine currents and voltages. MATLAB software is used for design simulation of the estimators while Texas Instruments TMS320F2803x, power module with space vector modulation, inverter and code composer studio for software development, is used for practical experimentation. PI controller was used for both speed and current controller. The simulation and experimental result demonstrated good dynamic and steady state performance 3.38% overshoot and 31.4 rad/sec bandwidth have been achieved with 0.00375 steady state error.
