LabVIEW 8.5 Expands Control Design And Simulation Module February 26, 2008
The release of the NI LabVIEW 8.5 control design and simulation module adds features that help to analyze open-loop model behavior, design closed-loop controllers, simulate systems, and create real-time implementations. The latest version of the module introduces design features such as analytical proportional integral derivative (PID) for improving system closed-loop stability and model predictive control to multivariable systems. It also expands support of LabVIEW MathScript with the addition of 18 .m file functions to ease creating models, defining how models are connected, and analyzing system stability. Other enhancements include model predictive control (MPC), a popular algorithm for controlling multiple input, multiple output systems in process control applications. Users can exploit the MPC feature to construct controllers that adjust the control action before a change in the output set point actually occurs. Pricing for the module starts from $2,999.
