Abstract
This paper deals with implementation of vector controlled induction motor drive (VCIMD) using DSP TMS320F240 and a comparison between proportional integral (PI) and fuzzy pre-compensated proportional integral (FPPI) speed controllers. The power circuit consists of a three-phase IGBT based voltage source inverter (VSI) feeding a three-phase squirrel cage induction motor. The control circuits consist of sensing circuits, interfacing circuits and control software. The sensed speed (ω <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> ) and the sensed winding currents in two of the three phases (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">as</sub> and I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">bs</sub> ) are used as feedback signals for the closed loop control structure. Test results are presented for drive starting, speed reversal and load perturbation modes using PI and FPPI speed controllers respectively and the advantage of precompensation is demonstrated in detail.
