An FPGA/SOPC open system for designing and testing controllers

This paper presents an open system for designing and testing electronic control units of fast automotive control systems in order to build a prototype quickly and implement the real-time simulation verification. It integrates hardware, software and algorithms on a single FPGA. FPGA board can be used for hardware and a Nios II-based SOPC (System-on-a-Programmable- Chip) system is used to implement software and algorithms. Finally, we implement and test a PID algorithm and a model predictive control algorithm for controlling an electronic throttle by dSPACE or xPC-Target. The results verify the functionality of the developed system.
