LQG Synthesis

LQG Synthesis Window Anatomy

© National Instruments Corporation
This chapter discusses the LQG Synthesis window, which is used to
synthesize a linear quadratic Gaussian (LQG) controller for a SISO plant.
If you select LQG synthesis with a MIMO plant, you will get the MIMO
LQG Synthesis window described in Chapter 12,
Synthesis.
The LQG Synthesis window is shown in Figure 7-1. From top to bottom,
it contains:
• 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 four design parameters:
– Control cost parameter ( )
– Sensor noise parameter ( )
– Integral action time constant (T
– Decay rate or exponential time weighting parameter (a)
These parameters are described in greater detail later in this chapter.
