Synthesis Modes and Window Usage
In addition to the standard LQG/H
∞ synthesis, any combination of three
additional features is supported:
• Integral action
• Exponential time weighting (guaranteed decay rate). This feature is
only enabled in the case of LQG design.
• Input and output weight editing
In the Main window, the synthesis mode is reported in the text in the titlebar
at the top. The Int Time (integral action time) toggle button enables
and disables integral action. The Decay Rate toggle button controls
exponential time weighting. The Weight Edit toggle button enables and
disables output weight editing. The Hinf Bound toggle button enables and
disables design mode.
