  Researchers as well as the industries have great interest in energy efficient operation of Induction Motor Drives (IMD). This can be achieved if the IMD is operated at its maximum efficiency under different loading conditions. In this study, the on-line voltage/current V/I control scheme to operate IMD at its maximum efficiency is introduced. The steady-state per phase equivalent circuit of induction motor is used to derive the V/I reference expressions. The control method requires supplied current, voltage, frequency and motor constants to achieve the maximum efficiency operating region. The V/I algorithm is realized through a control software and single-chip 3-phase AC motor controller, MC3PHAC supervised by Personal Computer (PC). Experimental result shows that V/I ratio under different loading conditions met the targeted value by changing the modulation index. The proposed method is suitable to low horsepower HVAC motors where oversize and/or have a wide load variation.

  This research focus on the software that called Fuel Consumption Cost Estimator (FCCE) that will give a total estimation for fuel consumption. FCCE is an automated system that will calculates the total amount of fuel cost for a car to travel based on the distance given to get to the destination. The calculation is based on Parametric Estimating method. By using this system, the user will get a summary which based on the userís data and will give the best solution to estimate the minimum cost towards the desired destination. FCCE has been successfully developed and tested in the single client server environment.
