Simulation module

National Instruments’ LabVIEW Simulation Module 2.0 extends the LabVIEW graphical development environment for the modelling, design, simulation and real-time implementation of control systems.

With the latest upgrade to the software, design engineers can more easily analyse complex, nonlinear control systems using new optimisation, model trimming and linearisation and decrease development time with new performance improvements.

The LabVIEW Simulation Module 2.0 allows designers to develop controllers ranging from simple PID to multivariable LQG and nonlinear control systems. Engineers specify controller structure, cost function and constraints, and the module automatically determines optimal controller gains. In addition to tuning controllers, engineers can use the software to optimise dynamic system parameters for other design objectives such as stability or vibration reduction.

The upgraded software also includes enhancements for model trimming and linearisation. Engineers now can linearise complex, nonlinear systems modelled in control block-diagram form and use the LabVIEW graphical development environment for the entire development process.

Engineers can seamlessly download their models built with the simulation node to a real-time target using the LabVIEW Real-Time Module. For applications such as rapid control prototyping or embedded implementation, engineers can use the LabVIEW Simulation Module with the NI CompactRIO embedded system, a small and durable platform based on FPGA technology. For hardware-in-the-loop testing applications that require high-speed computation capability, they can use NI real-time PXI targets.
