Dynamically reconfigurable DC motor control system based on co-design methodology

The design of embedded control systems is rapidly change during the last decade. Guaranteeing the safety of these systems is a very challenging topic. It is possible to identify two main factors that are involved in the control of those systems: Hardware/Software (HW-SW) codesign and dynamic reconfiguration. Furthermore, the use of an embedded operating system associated with a functional module library is required for the establishment of an efficient co-design solution. This paper aims to propose an appropriate co-design methodology for closed loop DC motor control based on Field Programmable Gate Arrays (FPGA) and low cost platform Beaglebone board supported by a Linux operating system. The dynamic reconfiguration of the control system is provided by an embedded web server implemented on Beaglebone.
