A design framework for FPGA-based dynamically reconfigurable digital controllers

During the past years, it has been shown that dynamic reconfiguration of FPGAs can be used to enhance the resource efficiency and flexibility of digital controllers. The authors have developed a system architecture, which allows the reconfiguration of FPGA-implemented controllers during runtime. Depending on the operating regions of the controlled plant different controllers can be dynamically loaded into the system. In this paper we present a design flow that enables an automated generation of such partial controllers. Furthermore, a high-level design entry allows a comfortable simulation of the controllers with sophisticated tools such as Matlab Simulink.
