RT-LAB: Add Real-Time & HIL to Simulink Non-Real-Time Models


Originally developed for the Canadian Space Agency, RT-LAB allows very large Simulink® models with very large I/O counts to be run in real-time with HIL.

It does this by sharing the computational load over multiple CPU cores on the real-time computer, or across multiple simulators connected via optical fibre links.

This makes RT-LAB ideal for mechatronics, power electronics, power systems (including microgrids) and mixed format (ie heterogeneous) modelling and analysis.

Because it leverages existing Simulink modelling expertise and libraries, it's the preferred real-time simulation solution in university teaching and research labs around the world.

And it includes optional solvers, libraries and utilities that add unparalleled flexibility across multiple disciplines.

eFPGASIM options

For real-time simulation of models created in:

  • PSIM
  • PLECS
  • NI Multisim

Includes solvers and libraries for:

  • Electronic circuits
  • High-fidelity FPGA-based simulations

eHS Solver allows models created in SPS, PSIM, PLECS or Multisim to be brought into the RT-Lab simulation environment. It automatically programs the simulator FPGA to address higher resolution simulations in the 2ns - 2us time-step range, without users needing any FPGA or VHDL programming expertise.

RT-XSG is an option that provides ready-made Simulink functional blocks for FPGA Hardware-in-the-Loop and Rapid Control Prototyping simulations. It allows users to custom configure the simulator's FPGA and to manage high-bandwidth data transfer between the RT-LAB software running on the CPU cores and the user-defined systems on the FPGA.

The eFPGA Electric Machine Library option (now included with RT-XSG) provides a wealth of device models, including permanent magnet, asynchronous machines, stepper and other motor and generator types. The models contain dedicated I/Os for PWMs, resolvers, encoders and hall effect sensors. All I/Os can be reconfigured through the RT-XSG option and the models themselves can be edited via the eHS front end.

The MMC FPGA blockset simulates MMCs with very high fidelity and unbeatable efficiency. The models can be seamlessly integrated into a complex electric circuit simulated in eFPGASIM/eHS (see also HYPERSIM). The blockset is directly accessible from MATLAB/Simulink, enabling users to further edit models and produce their own FPGA firmware (see also RT-XSG option) for integrating special I/O interfaces or customised control algorithms.

ePHASORSIM options

For real-time simulation of models created in:

  • Excel
  • PSSe
  • CMYE
  • DigSILENT
  • PowerFactory
  • OpenModelica

Includes solvers and libraries for:

  • Very large transmission & distribution grid phasor stability studies

ePHASORSIM's phasor domain solver, performing at a typical time-step of few milliseconds, provides voltage and current information equivalent to those of a phasor measurement unit (PMU) installed in a power grid. This unique electromechanical real-time simulation system enables precise modelling and analysis of large-scale networks - as large as 106,000 nodes (verified) - within a real-time desk-top environment.

It allows the development of complex transmission and distribution network models in Simulink, PSS/e and other modelling tools, which can then be verified 'offline' (ie on a PC's CPU in non-real-time mode) or 'online' (ie on the simulator hardware where dynamic optimisation shares processing tasks across available CPUs and FPGAs).

This level of accuracy and ability to scale from the small to the very large makes it ideal for testing and integration of EMS/SCADA systems, and wide area protection and control schemes.
