Power Hardware-in-the-Loop (P-HIL) Simulation

Speedgoat provides a wide range of real-time P-HIL solutions to test and verify power electronics and power system components. Utilize complex physical models designed with MathWorks tools - such as MATLAB, Simulink, Simulink Real-Time, Stateflow, Simscape or Simscape Electrical (formerly SimPowerSystems) - on multi-core CPUs and FPGAs with the highest level of performance.

Test hardware components with electrical power interfaces using P-HIL simulation with round-trip latencies of 1 microsecond and power levels from just a few watts to megawatts. Typical applications include:

  • battery management system with battery cell emulation
  • electric powertrain test-rigs with 3-phase AC power
  •  integration of renewables to the power grid.

Speedgoat works together with power supply manufactures such as EGSTON Power to provide the lowest power HIL round trip latencies.

Speedgoat real-time target machines are equipped with specialized I/O modules and enable the simulation of devices such as:

  • absolute and incremental encoder sensors
  • high-precision thermocouples
  • strain gauges
  • transformers with LVDT/RVDT or synchro/resolver interfaces
  • power electronics components by leveraging FPGA-based modules with analog and digital I/O

 In addition, a wide range of communication protocols are available, from CAN, FlexRay, ARINC 429, MIL-STD-1553, EtherCAT, real-time UDP to XCP.

  • Create real-time applications to run on Speedgoat systems using Simulink Real-Time
  • Create plant designs using Simulink and powerful physical modeling tools such as Simscape, Simscape Electrical or Simscape Multibody at different levels of fidelity:
    • Phasor (milliseconds)
    • Power Systems (hundreds of microseconds)
    • Power electronics (microseconds)
  • Drag and drop Speedgoat I/O driver blocks to your Simulink model and configure signal parameters via easy-to-use dialog fields
  • Autogenerate C/HDL code from Simulink controls design and execute on multi-core CPUs and optional FPGAs
  • Implement your plant design and run on the real-time system within seconds
  • Tune signal parameters on the fly during real-time execution and immediately monitor the effects
  • Automatically perform a wide range of tests using Simulink Test, MicroNova EXAM, Tracetronic ECU-TEST, MATLAB scripts or Simulink Real-Time explorer
  • Create graphical user interfaces simply using Simulink Real-Time together with MATLAB App Designer and .NET or C/C++ interfaces


Save costs and reduce risks

  • Reduce costs by increasing development speed including continuous verification and validation
  • Perform tests beyond the range of normal parameters or plant capabilities without risking damage to equipment
  • Lower innovation costs by being able to continuously try new ideas even when the full plant is not available

Shorten time-to-market

  • Shift the traditional sequential V-diagram to a circular workflow to enable continuous verification and validation of your designs at the earliest possible stage
  • Unlike physical plants, real-time simulators can easily be expanded with new I/Os at any time
