| Summary: | The proportional integral (PI) repetitive controller that is applied to the three phase
inverter for the three phase induction motor is developed. This project is about to
design a combination of PI-Repetitive controller simulation and fabricating the
hardware to control the speed of a three phase induction motor. The controller
eliminates the periodic errors on the output current due to inverter current nonlinearity
and load disturbances. The controller is implemented on a gate driver, three phase
inverter and filter prototypes which are constructed in laboratory. Open-loop and
closed-loop condition are verified by means of simulation and experiments in order to
investigate the stability of controller. The result of the controller’s performance
between simulation and hardware are explained in this report in terms of the PWM
output and three phase inverter output waveform. The PI-Repetitive controller will
solve the starting problem of the three phase induction motor and minimizes the line
current error to maintain the required steady state condition. |
