Real Time Platform for Rapid Prototyping and On-line Simulation of Digital Controllers for Electrical Drives

This paper presents a concept and an implementation example of a rapid prototyping platform, which permits to run simulation models on real-time hardware. The key components of the presented platform are a very powerful floating-point digital signal processor and a field programmable gate array. Furthermore the system includes analog inputs and outputs and a high-speed IEEE1394 communications interface. Using the proposed setup the developer has a proprietary real-time operating system, various hardware drivers and motor drive peripherals at one's disposal. A hardware-in-the-loop (HIL) test plant for integrated electrical drives is shown as an implementation example for automotive applications. Such applications may be electrical drives for hybrid electric vehicles or electrified auxiliary power units.
