1. Launching the System Identification Assistant

You can use the LabVIEW System Identification Assistant to create dynamic models of system data. In the following exercises, you create a dynamic model that relates the voltage of a DC motor to its motor speed.

Complete the following steps to launch the System Identification Assistant in the default configuration if you have not already done so.

1. Launch the System Identification Assistant by selecting Start»All Programs»National Instruments»LabVIEW System Identification Toolkit»LabVIEW System Identification Assistant. The System Identification Assistant launches within the LabVIEW SignalExpress environment.
   
   You also can launch the System Identification Assistant from Windows Explorer. Browse to National Instruments\MAX\Assistants\SysId Assistant and double-click SystemIdAssistant.exe.
   
   To launch the System Identification Assistant from LabVIEW, select Tools»Control Design and Simulation»Launch System Identification Assistant.
2. The Welcome dialog box and the LabVIEW SignalExpress environment open in the default configuration.

   Note  You can place a checkmark in the Show At Startup checkbox in the Welcome dialog box to specify whether the Welcome dialog box appears when you launch the System Identification Assistant. You can display this dialog box at any time by selecting Help»Show Welcome Dialog.

   The Project View is the blank white rectangle on the left side of the LabVIEW SignalExpress environment. The Data View is the green coordinate grid on the black background in the middle of the LabVIEW SignalExpress environment. The context help window is the window on the right side of the LabVIEW SignalExpress environment that displays the How do I get help? and Context Help topics.
3. Click the Close button to close the Welcome dialog box.
