SIMULINKÂ BLOCKSET
PART OF THE ACG SDK
The Simulink blockset contained within ACG SDK enables graphical converter control software design and implementation. It transforms imperix controllers into a fully-compatible Simulink Coder targets.
The blockset takes advantage of both the simulation and code generation engines of Simulink to support easy converter control development and maintenance.
MAIN BENEFITS
- Ease of use: Accessible and fast graphical programming thanks to automated code generation.
- Accurate modeling: Advanced simulation models for faithful offline simulation results.
- Extensive capabilities: Broad range of specialized functions such as ADC, PWM modulators, etc…
- High performance:Â Transparent use of optimized driver methods for uncompromised performance.
- High flexibility: Easy integration with custom FPGA-based developments, offering boundless possibilities.
 Create Simulink model Start from scratch, adapt an existing control model, or use one of the code examples available on the imperix knowledge base. |
 Run offline simulation You can test your control on a simulated converter model first. Then, you can rely on the obtained results to switch to real power. |
 Auto-generate code In just one click, Simulink Coder transforms your model into code that is loaded and executed on your imperix target, thanks to a fully integrated toolchain. |
 Capture results The transient generator and datalogging features of Cockpit will challenge your control and export the results for your next publication. |

Thanks to the layered structure of the embedded operating system, Simulink has access to the exact same drivers as the C++ routines. This guarantees the best possible performance as well as a rigorous supervision of possible hardware misconfigurations.
FPGA CUSTOMIZATION
For demanding applications, parts of the runtime control can be offloaded inside the user-programmable portion of the FPGA. For this, Simulink has interface blocks readily available, exchanging data with the FPGA sandbox (SBI and SBO peripherals).
SOFTWARE LICENSING
The licensing policy of ACG SDK authorizes downloading and installing the software on an unlimited number of computers. As such, offline simulation is always possible. A license is only required to load and execute the control code onto a real-time control target (e.g. B-Box).

ACCURATE SYSTEM MODELING

The control model, on the left, contains the portion of the system that is meant to be executed on the B-Box or B-Board controller. As such, it contains the peripheral blocks and the control algorithm itself, which can be translated into code.
The plant model, on the right, contains a simulation model of the controlled power converter and the related equipment. It can be either implemented using Simscape Power System, or PLECS Blockset.
SAMPLING INSTANT
The ADC block’s simulation model, combined with the sampling clock signal, ensures that the measurements provided by the plant model are sampled at the correct frequency and with the right phase. In this way, the simulated controller can work with the exact same samples as a real controller.
PWM PHASE-SHIFTS
The carrier-based modulator block lets you freely configure the carrier phase-shift, even in run time at each interrupt execution. In addition, the block’s simulation model uses a PWM clock signal to guarantee a precise timing of the generated switching edges, using the exact same logic as the imperix controllers.
COMPUTATION TIME
When applications grow in complexity, the non-zero computation time of the control algorithm introduces an extra delay in the control loop. This phenomenon is very often neglected in RCP systems, but thanks to the simulation models of ACG SDK, it can be anticipated and the control tuned accordingly.
Flexible monitoring options
SIMULINK EXTERNAL MODE
While code is running on an imperix target, External Mode allows you to monitor and modify any real-time variable on the fly, directly from Simulink. This can even be used to create stunning personalized Graphical User Interfaces using Simulink’s App Designer.
DATALOGGING
Thanks to Imperix Cockpit and its remote monitoring tools, each and every sample of any variable can be monitored in an oscilloscope-like interface. This is also the best way to export all your results in CSV format to analyze or post-process them with the tool of your choice.
REAL MEASUREMENTS
When it comes to debugging, sometimes there’s nothing like your beloved oscilloscope! For easy interfacing with a B-Box RCP, we provide 4 handy analog outputs with SMA coaxial connectors that will let you scope any controller variable alongside your real measurements.
