Abstract

In this paper Field Programmable Gate Array (FPGA) system level based methodology for control system design is proposed and described in details on the case study of three-axis positioning controller implementation. System level design tool, such as Xilinx System Generator (XSG), provides Simulink based FPGA design and automatic converting of XSG model into efficient Very high speed integrated circuit Hardware Description Language (VHDL) code, increasing productivity by reducing the design time. The optimal design, in terms of FPGA recourse occupancy, is provided using restructuring data flow graph (DFG) of control algorithm and specifying the optimal fixed-point format. The proposed approach is validated through real experiments on three-axis didactic radar platform.
