Run the system inside Windows using variable or fixed-step solvers to verify the mathematical soundness of the controller.
Starting with LabVIEW 2021, the module was exclusively available for purchase as part of the . For earlier versions (e.g., LabVIEW 2020), a compatible version of the module could still be purchased as a separate add-on.
Once a model is built, the module features built-in tools to extract vital stability and performance metrics. Users can instantly generate classical control analytics such as Root Locus, Bode plots, and Nyquist diagrams, as well as calculate phase and gain margins to ensure system robustness before any hardware loop is closed.

This combination of a specialized simulation loop and a visual modeling interface created a powerful environment for control engineers.
The LabVIEW Control Design and Simulation Module is a powerful tool for engineers and researchers working on control systems, mechatronics, and robotics. With its comprehensive platform for designing, testing, and validating control systems, the module offers improved productivity, accuracy, and flexibility. The 2018 and 2021 versions of the module introduce several new features and improvements, including enhanced simulation, new analysis tools, and improved code generation. Whether you are working on control systems, aerospace and defense, automotive, or industrial automation applications, the LabVIEW Control Design and Simulation Module is an essential tool for unlocking the power of control systems design and simulation.
Choosing the wrong ODE solver will cause your simulation to stall or become unstable. If your system includes sudden, sharp discontinuities (such as hard mechanical stops, saturation limits, or digital switching), use a like ODE 1 (Euler) or ODE 4 (Runge-Kutta) rather than a variable-step solver. This guarantees deterministic execution times when migrating to real-time hardware. 2. Avoid Memory Allocation inside the Simulation Loop

The Control Design and Simulation Module is extensively used across industries to bridge the gap between design and physical implementation.
The information presented in this article is based on official documentation and community knowledge as of its creation. Software features, system requirements, and support statuses are subject to change by the vendor (NI). Users are strongly encouraged to consult the official NI website and documentation for the most current information regarding product lifecycles and support policies.
Place a block inside the simulation loop to calculate error (Commanded Value minus Plant Output). Insert a Continuous PID block from the Simulation palette. Wire the error signal into the PID block input. Once a model is built, the module features
The 2018 version represents one of the most mature iterations of the classic NI software ecosystem.
The version of your CD&S module must exactly match the version of the base LabVIEW development system installed on your machine. For example, the 2019 Simulation module will refuse to install or execute if paired with LabVIEW 2020 Base/Full/Professional.
Develop controllers, such as PID or pole-placement controllers.
In 2018, many industrial systems still relied on Windows 7 and legacy real-time operating systems like Phar Lap. The 2018 version of the module was highly valued for its backward compatibility. It allowed engineers to maintain legacy automated test equipment (ATE) while utilizing robust simulation loops. The LabVIEW 2021 Shift
