Design of an optimized IC for control algorithms of AC machines: system testing and application

The paper deals with the integration of a control algorithm for alternative current (AC) motors using a co-design methodology for mixed hardware/software implementation. The authors mainly focus on two points: the co-design flow with the associated tools and a full hardware integration with a programmable FPGA device. They also present the interest in using the CORDIC (COrdinate Rotation DIgital Computer) algorithm as a mathematical processor. This study is part of project that investigates firstly, the co-design methodology in order to optimize the integration of control algorithms using hardware, software or mixed resources, and secondly the development of machine diagnosis routines.
