The methodology is based on dividing large tasks into smaller blocks and constructing the flow block diagram within the Incremental System Build (ISB) levels logic frame, by using re-useable s/w modules from Texas Instruments TM (TI TM) library, from the Target Support Package TM TC2000 library and by developing custom s/w modules in MATLAB® environment. The block algorithmic code is build up by interconnecting the various s/w modules in Simulink®. The native MATLAB® m-files are translated to ANSI®/ C code with Real-Time Workshop®. The Code Composer Studio TM (CCS) IDE for the C2000 series compiles and download the C code through a JTAG emulator to the Digital Spectrum eZdspF2812 TM . The proposed methodology is applied for the implementation of the algorithm of an innovative hybrid fuzzy efficiency control scheme which is incorporated to an ordinary Field Oriented Control (FOC) drive, in order to improve online the efficiency for various types of motor drives (i.e ACIM) for both steady state and transient state operation under load and speed variations. http://creativecommons.org/licenses/by/4.0/The Online Journal on Power and Energy Engineering 12 Sergaki Eleftheria Σεργακη Ελευθερια Afentakis Nikolaos M.
