Abstract: This study presents a Top-down methodology for hardware rapid prototyping of integrated Direct Torque Control of Induction motor drive control, based on Hardware Description Languages (HDL’s). This methodology is a set of procedures and Computer Aided Design tools to optimize development time, final product cost and reusability of the digital electronic system design. The use of HDL’s provides continuous checking of functional validation of the control and makes the digital design independent of the target technology. More, HDL’s are common languages throughout all design stages. The three stages of the methodology are discussed. The behavioral stage defines control functionality at system level and allows the study of Integrated Circuit digital properties. In the structural stage, the design is defined as a set of components and interconnections. Finally, in the physical stage implementation technologies, FPGA is considered. Matlab/Simulink is used to validate the algorithm. This study presents an application of the methodology to the integration of Direct Torque Control (DTC) of an induction machine. First of all, the DTC principle is described. Then, step by step, the behavioral, structural and physical stages of digital control representation are discussed and results are validated.
