LQG/H-Infinity Main Window

© National Instruments Corporation
This chapter describes the MIMO LQG/H Synthesis window. The
LQG H window is used to synthesize both LQG and H controllers.
The two design methods have been combined in a single window because
of the similarity regarding the use of weights: constant weights,
frequency-dependent weights, and integrators.
The MIMO LQG/H Synthesis window consists of a main window and
four auxiliary windows for editing constant weights, frequency-dependent
weight functions, decay rate, and performance level.
The LQG/H Main window is shown in Figure 12-1. From top to bottom,
it consists of:
• A menu bar with entries Special, Edit, View, and Help.
• A message area that describes the synthesis mode (type of controller),
for example, LQG with integral action.
• A control panel for changing the five design parameters:
– Control cost parameter ( )
– Sensor noise parameter ( )
– Integral action time constant (T
– Decay rate or exponential time weighting parameter (a)
– H performance level ( )
