A digital control system based on codesign technology

In recent years, the ever-increasing capabilities of microelectronic devices allow the implementation of more sophisticated speed drives. The control structure performs a greater number and a wider range of functions. The difference in the nature of these functions pushed the designer to investigate the architecture on the hand, and the implementation on the other hand. A control system implemented on Codesign technology allows the use of the advantages of DSP in numerical calculation and FPGA in logical computation. The definition of system (FPGA and DSP) is reviewed and the reasons for this choice are discussed. The advantages of this technology are discussed as well as the difficulties encountered at the development stage
