Evaluation of SoC-based embedded Real-Time simulators for electromechanical systems

Embedded real-time simulators for electromechanical and power electronic systems using system-on-chip devices

“…Compiler optimization options are used to infer automatic vectorization which implies arranging data and operations in a proper way to be executed by the NEON SIMD and the VFPv3 FPU at a CPU clock frequency of 667M Hz. In some cases it reduced the execution time by 80% while maintaining the same precision in the results [16].…”

“…Some simplifications are adopted like neglecting the saturation, hysteresis and iron losses, and not considering the temperature effect on the windings. More information about the model, the dq reference frame equations, and the discretization method utilised can be found in previous works of the same authors [16].…”

“…Having in mind all these potential features, the proposed paper can be seen as an extension of works [12,16] and its aim is to evaluate these SoC platforms through the development of complex eRTS. The Xilinx's Zynq-7000 All Programmable SoC device has been chosen and two case studies have been maintained: the eRTS of a Doubly Fed Induction Generator (DFIG) and the one of a Modular Multi-Level converter (MMC).…”

Embedded Real-Time Simulator for Sensorless Control of Modular Multi-Level Converters

“…In the proposed application, a Xilinx Zynq SoC-FPGA device is used to ensure fast execution, thanks to the inherent PL resources, as well as a high level of integration, having in mind the hardwired ARM cortex-A9 processor, the distributed memory resources and also the analog-to-digital conversion (ADC) peripherals. The following subsections provide descriptions of the developed sensorless controller modules, but more details regarding the whole digital implementation can be found in [29], including a dedicated design methodology. Furthermore, Refs.…”
