The LabVIEW Control Design and Simulation Module is an add-on for the LabVIEW programming environment designed to help engineers simulate dynamic systems, design controllers, and deploy control systems to real-time hardware. Spanning the versions from 2018 to 2021, the module evolved alongside the core LabVIEW platform to support more complex industrial and research applications.  Core Capabilities 

The module provides a comprehensive toolset for the entire control system lifecycle: 

System Identification: Build mathematical models based on measured stimulus and response data.

Analysis & Design: Analyze open-loop model behavior and design closed-loop controllers using both classical and state-space techniques. labview control design and simulation module 2018 2021

Simulation: Use ordinary differential equation (ODE) solvers to recreate and analyze the behavior of dynamic systems in software, reducing development costs.

Deployment: Deploy algorithms directly to NI real-time embedded hardware for rapid control prototyping (RCP) or hardware-in-the-loop (HIL) testing.  Key Version Features (2018–2021) 

During this period, the module maintained a consistent core feature set while adapting to new operating systems and hardware. 

LabVIEW 2018: Focused on robust support for 32-bit Windows, including the Control Design Assistant and System Identification Assistant for interactive design.

LabVIEW 2020: Introduced broader support for modern operating systems, including Windows 10 (version 1909), macOS 10.14/10.15, and 64-bit Linux distributions like Red Hat Enterprise 8 and CentOS 8. [1] National Instruments

LabVIEW 2021: The last major release before significant changes to the module's lifecycle. It requires a Full or Professional Development System and at least 800 MB of disk space. It notably includes support for Python 3.6 through 3.9 within the broader LabVIEW environment.  LabVIEW Control Design and Simulation Module Download - NI

Here’s a helpful, structured guide to understanding and using the LabVIEW Control Design and Simulation Module for versions 2018–2021.

Note: NI (now part of Emerson) rebranded this module. In 2021, it became part of the LabVIEW Control Design and Simulation Module (same name). From 2020 onward, it requires the LabVIEW Professional development system.

Workaround for 2021 multi-core: Partition plant into subsystems, run in parallel using Channel Wires or TDMS streaming to separate loops.
