Model-based design approach for embedded digital controllers design

Abstract

Modern embedded systems are rapidly becoming a driving factor of the explosive growth of e-industry due to their increasingly sophisticated functionalities and complex features. At the same time, the advances of microelectronics and semiconductor technologies have enabled to increase the capacity-level integration of digital circuits like field programmable gate array (FPGA). The design of their systems is based on the challenge of increasing their performance by an abstraction of their implementation details to manage complexity. Designers need a more direct path between the specification and implementation. Different approaches to high-level synthesis design methodologies are currently used for high description language code generation. This paper examining a case study of the model-based design (MBD) approach using Xilinx System Generator, validated on two control drive applications such as direct current motor and alternative current motor. Results indicate that MBD approach enables designers to implement advanced algorithm including complex computing with good data precision and limited FPGA resources.
