ICDM Main Window
This chapter describes the use of the ICDM Main window, which is used to
perform the following functions:
• Communicate with Xmath—for example, transfer plants/controllers
from/to Xmath
• Display warning and log messages
• Display a variety of standard plots
• Select a synthesis method for controller design
• Control several auxiliary windows (for example, Ranges, Alternate
Plant)
Notice that the ICDM Main window is not directly used to design the
controller. It is used to make high level decisions, such as which synthesis
method to use, and to view or analyze the response with the current
controller.
This chapter is limited to the discussion of SISO design. For MIMO design
information, refer to Chapter 11,
Introduction to MIMO Design .
Window Anatomy
The ICDM Main window, shown in Figure 3-1, consists of the following
elements, from top to bottom:
• A menu bar with File, Edit, Plot, Synthesis, and Help menus.
• A scrolled text area for warnings and messages. You can resize this
area independently of the rest of the ICDM Main
window. The log
messages that appear here are meant to give a rough trace of your
ICDM design session. It records major actions such as reading a
new controller or plant in, opening a new synthesis window, saving
controllers to the history list, and so on.
• A line that gives the plant name.
