XSG Electric Component Models

Plant models for FPGA-based simulations

Simulation of electric components that require highest dynamics and precision.

Application Area

Electric motor control applications that demand very high precision and correspondingly high sample rates are simulated best on field-programmable gate arrays (FPGAs). To support identical workflows for controller development and testing, the XSG Electric Components Models (closed-loop simulation components) are implemented as Xilinx® System Generator (XSG) models that run on a dSPACE DS5203 (PHS systems) or DS2655 (for SCALEXIO) FPGA Board. Closed-loop simulations of electric devices and their controls are supported at very high sampling rates in real time.

Direct FPGA I/O Access

In addition to the plant models, the XSG Electric Component Library is supplemented by enhanced I/O functions from the XSG Utils Library on the DS5203/DS2655 FPGA Boards, e.g., for timing analysis and capturing digital input sources. The XSG Electric Components Library and the DS5203/ DS2655 FPGA Boards can be used together for E-motor simulation both on signal and on power level. The XSG Utils Library is required additionally.
