The LabVIEW Control Design and Simulation (CD&S) Module saw significant stability improvements and workflow refinements between the 2018 and 2021 releases. While the core mathematical solvers remained largely consistent, the updates focused on improving cross-platform compatibility and integration with external scripting languages like Python and MATLAB. Key Evolutionary Changes (2018–2021)
Simulation Model Converter (2018): A major addition in the 2018 version was the ability to convert .slx model files (typically from Simulink) directly into LabVIEW VIs with a simulation diagram.
External Integration (2021): The 2021 release brought a dedicated MATLAB node for direct interaction with .m files and updated the Python node to support Python 3.9.
Security and File Transfer: The 2021 module introduced SFTP support for secure file transfers, which is critical when deploying control models to remote real-time targets.
UI Modernization: LabVIEW 2018 introduced NXG Style controls, allowing simulation front panels to match the modern aesthetic of the then-emerging NXG platform. Core Module Capabilities
Across both versions, the CD&S module provides a standardized toolset for the entire control lifecycle:
System Identification: Build mathematical models from measured stimulus and response data.
Analysis & Design: Tools for root-locus, Bode plots, and state-space to transfer function conversion. labview control design and simulation module 2018 2021
