In this thesis project, a vector control system for an induction motor is implemented on an evaluation
board. By comparing the pros and cons of eight candidates of evaluation boards, the TMS320F28335 DSP
Experimenter Kit is selected as the digital controller of the vector control system. Necessary peripheral
and interface circuits are built for the signal measurement, the three-phase inverter control and the system
protection. These circuits work appropriately except that the conditioning circuit for analog-to-digital conversion
contains too much noise. At the stage of the control algorithm design, the designed vector control
system is simulated in Matlab/Simulink with both S-function and Simulink blocks. The simulation results
meet the design specifications well. When the control system is verified by simulations, the DSP evaluation
board is programmed and the system is tested. The test results show that the current regulator and the speed
regulator are able to regulate the stator currents and the machine speed fast and precisely. With the initial
values of the motor parameters there is a 12.5% overshoot in the current step response. By adjusting the
stator resistance and the inductance this overshoot could be removed and only minor difference remains
between the simulated and measured current step responses
