XSG Electric Component Models

Plant models for FPGA-based simulations

Simulation of electric components that require highest dynamics and precision.

  • Simulation of extremely time-critical applications
  • Support of very high oversampling rates
  • Direct I/O access
  • Open models

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 contained 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.
