RT-DAC/OMNI real-time software success story

The RT-DAC/OMNI real-time teaks generation package was successfully applied to control the power electronics Dynamic Voltage Restorer (DVR). The DVR unit requires meeting hard real-time constraints, or else it may lead to the destruction of the equipment. The development path was presented at the International Symposium ELMAR 2017 and is described in the paper:

Firlit, A., Kolek, K., & Piatek, K. (2017). Rapid controller development for a dynamic voltage restorer. 2017 International Symposium ELMAR. doi:10.23919/elmar.2017.8124476

The paper is available in the IEEE Xplore Digital Library.

Sub-microsecond jitter of the RT-DAC/OMNI real-time software

The real-time applications generated automatically from Simulink diagrams and executed by the RT-DAC/OMNI boards are characterized by the sub microsecond scheduling jitter. The scheduling jitter in real-time systems is the irregularity of the beginning of the ex*****on of the periodic tasks. The picture presents the histogram of the periods between the consecutive entries to the periodic task. The frequency of the periodic task was 16 kHz and the jitter remains below 300 nanoseconds. The 300-nanosecond period determines the punctuality of the signal processing and generation of the control outputs.
It should be highlighted that the real-time application was automatically generated from the Simulink diagram.
