| RT Box: Automated Testing Application using Robot Framework |
For automated test environments the RT Box can be controlled via external scripts using an XML-RPC interface. XML-RPC is a lightweight protocol for executing functions on a remote machine. The RT Box acts as an XML-RPC server, which processes requests sent from scripts running on another computer. Many scripting languages support XML-RPC out of the box, for example Python. For test automation the XML-RPC interface can be used together with the open-source automation framework “Robot”. This demo shows how to set up a basic automated test for the RT Box by using the XML-RPC interface of the RT Box and the Robot Framework. It also provides a basic Robot library file that can be used for any user-defined automated tests and list the XML-RPC API of the RT Box. Tags: |

| RT Box: Brushless DC Machine Demo Application for LaunchPad-Nucleo Interface Board |
The LaunchPad-Nucleo interface board from Plexim ships with a pre-programmed LaunchXL-F28069M so users can quickly start using the RT Box with an example hardware-in-the-loop application. The control logic pre-programmed on the microprocessor (MCU) is a basic trapezoidal control application for a brushless DC (BLDC) machine. This demo includes an RT Box model of the BLDC drive to use with the pre-programmed MCU and shows the basic steps required to use the RT Box. Tags: |

| RT Box: Minimal Example Demos |
These RT Box minimal example demos feature basic power converter topologies running on a single RT Box. The converter topologies are built with components under PLECS library Power Modules, in their default Sub-cycle average or Sub-step events configuration. The PWM signal generation uses a simple open-loop pattern, on the same RT Box where the converter topology runs in real-time. To deploy the model on a single RT Box, a loopback cable is needed to connect together the Digital Out interface and the Digital In interface at the front panel of the Box. Tags: |

| RT Box: Modular Multilevel Converter |
This RT Box demo model features a grid-connected modular multilevel converter (MMC) with open-loop controls. The demo model can be simulated either in single-tasking or multi-tasking mode using the Task Frame component. For real-time simulation on the RT Box 2 or RT Box 3 each specified task is executed on a different CPU core to reduce the overall discretization step size. For the PLECS RT Box 1 only single-tasking mode is available. Tags: |

| RT Box: Multistep Model Predictive Control for NPC Inverter Driving an Induction Machine |
This RT Box demo model features a medium voltage three-level neutral-point-clamped voltage source inverter driving an induction machine. The squirrel cage induction machine has a rated power of 2 MVA. The objective of the model predictive current controller is to control the stator currents along their time-varying reference, by manipulating the switch position, while minimizing the switching effort. The predictive controller uses a prediction horizon of Np = 5. An efficient optimization algorithm is used to solve the underlying optimization problem. Tags: |
