Selecting a Synthesis or History Window
The Synthesis menu in the ICDM Main window is used to select which
synthesis window will be active. If the current controller is compatible with
the requested synthesis window, then the synthesis window opens, and is
initialized with the current controller.
If the current controller is not compatible with the Synthesis menu
selected, then a dialog box appears that gives the user several options. If the
user proceeds in this case, the current controller will be replaced with the
previous design in the synthesis window selected. For example, if the Root
Locus Synthesis
window is open so that the current controller is a general
transfer function, and the user requests the LQG Synthesis window, a
dialog box will issue a warning that the current design will be overwritten,
and give the user the option of cancelling the request, proceeding, or
writing the current (Root Locus) controller to the history list before
proceeding. If the user proceeds, then the Root Locus
window will close,
the LQG window will open, and the current controller will be overwritten
with the controller from the LQG Synthesis window.
To open the History window, select Synthesis»History. Because all
controllers are compatible with the History window, the History window
will open with the current controller active. In other words, the current
controller will be saved on the history list (if it has not already been saved)
and made the active or selected controller on the history list.
Edit Menu
The Edit menu has two important entries:
• Selecting EditAdd to History, or typing h in the ICDM Main window,
will cause the current controller to be saved on the history list. You will
be prompted for a comment that will be saved along with the current
controller. Refer to Chapter 9,
History Window .
• Selecting Edit»Alternate Plant window causes the Alternate Plant
window to appear. Refer to Chapter 10, Alternate Plant Window .
