The HiL Solution from imc

With imc HiL, we are offering a turn-key solution for Hardware-in-the-Loop testing. imc HiL combines data acquisition, control, and simulation in a single system. Versatile interfaces such as EtherCAT, CAN bus, Profibus, etc. allow for quick integration in test environments. Moreover, imc HiL operates completely autonomous and without a controlling PC. In mobile applications in harsh environment conditions, for example, this proves to be quite advantageous.


imc HiL for Easy Simulations and Control Tasks:

Typical Applications:

  • Fatigue tests
  • Simple restbus (residual bus) simulation
  • Controls and control structures (PID control, cascade control, etc.)
  • Solutions to differential equation systems
  • And much more...

This solution is based on the following components:

1.) Modular imc measurement system

The modular measuring system imc CRONOScompact forms the basis of the imc HiL solution. It manages all the inputs and outputs, allows for compensations and analysis in real time and stores measurement and analysis data. Its modular architecture allows the system to be optimally adapted to the specific task. Various measuring amplifiers and modules allow direct connection of all common sensors.

3.) SYNTH-8 for imc CRONOScompact

SYNTH 8, the plug-in module for imc CRONOScompact, is a signal synthesizer which is able to play defined curve sections (signal profiles). This allows, for example, for the output of real load profiles or other control signals. It is also possible to generate signals out of functions, as well as to configure complex controls. A separate signal processor ensures that the calculations are not an additional burden on the measurement system.

2.) imc HiL Interface

The imc HiL hardware is a supplemental component for the imc CRONOScompact measurement system, which provides an xPC real time environment for Simulink models. imc HiL is fully integrated into the imc environment with direct, synchronized access to measured data, output, and control variables, as well as data storage management. By providing a dedicated processor for simulation and control, which is synchronized to the data acquisition system, the measurement operation (signal conditioning, filtering, sampling, triggering, data storage, etc.) and the simulation/control run synchronously and in parallel.

3.) Software component for imc HiL

The software component consists of a library of MATLAB / Simulink files and an extension of the measurement software imc STUDIO. Via the library, MATLAB / Simulink is extended to input and output blocks, on which the model is connected to the inputs and outputs of the imc system. The final configuration of the imc system takes place using the imc STUDIO measurement software.

Special features of imc HiL
