Engineers and scientists can use the MPC feature to construct controllers that adjust the control action before a change in the output setpoint actually occurs. The latest version of the module also includes model predictive control (MPC), a popular algorithm used in industry to control multiple input, multiple output (MIMO) systems in complex process control applications. The analytical PID feature provides engineers and scientists with functions to find sets of PID gain values automatically for a given system model, making it easy for them to avoid undesired behavior at design time and improve system stability. Historically, engineers and scientists have identified the proper PID controller gain values by experimentally tuning their controllers. When we achieved the results we wanted in simulation, we were able to reuse the graphical code created with the module and deploy it to real hardware and debug it – all within a single day.≊ new time-saving feature in the LabVIEW Control Design and Simulation Module is analytical PID capability. “The module made it easy for us to simulate our different control algorithms and test the code without the use of any hardware. m file functions to simplify such tasks as creating models, defining how models are connected and analyzing system stability.“The LabVIEW Control Design and Simulation Module significantly reduced the time it took us to develop the dynamic positioning on a split hopper vessel,” said Miguel Taboada, control engineer with SEAPLACE, an offshore and naval engineering company in Madrid, Spain. The LabVIEW Control Design and Simulation Module also offers expanded support of LabVIEW MathScript with the addition of 18 new. The latest version of the module introduces new design features such as analytical proportional integral derivative (PID) for improving system closed-loop stability and model predictive control to multivariable systems.

19, 2008 – National Instruments released LabVIEW 8.5 Control Design and Simulation Module, an extension of the LabVIEW graphical system design platform that helps engineers and scientists analyze open-loop model behavior, design closed-loop controllers, simulate systems and create real-time implementations.
