PROJECT TITLE :

Electric Machine Drive Design Improvements Through Control and Digital Signal Processing Techniques

ABSTRACT:

Developing the control algorithms of electric machine drives for less noise and harmonics is proposed here for style enhancements. Trendy management algorithms for electric machine drives are implemented, and their radiated magnetic fields are measured and imported into a digital Signal Processing unit. The measurement was implemented using magnetic field antennas that cover low frequencies. A digital signal processing unit was designed for on-line and real-time measurement and processing of the fields, and categorizing the harmonics. The controller compares the specified and measured signals and modifies the duty cycle of the switches to suppress the prevailing harmonics. The manual and automatic suppressions of some vital harmonics were implemented in 2 switching techniques employing a outlined procedure. Consequently, the modified management algorithm of the drive would radiate the electromagnetic stray field with less noise and harmonics. This ends up in lower electromagnetic interference from the machine drive. Since there is no would like to locate any sensor inside the machine or the converter, this can be considered as a nondestructive technique for industry implementations, where it is impossible to access the parameters of components for online monitoring.
