The technique of μ synthesis
extends the methods of H∞
synthesis to design a robust controller for an uncertain plant. You can
perform μ synthesis on plants with parameter
uncertainty, dynamic uncertainty, or both using the
musyn uses an iterative process called
D-K iteration to optimize the robust
H∞ performance of the
system. To get started with μ synthesis, see Robust Controller Design Using Mu Synthesis.
Use μ synthesis to design an unstructured robust controller or a fixed-structure robust controller for an uncertain plant.
You can sometimes improve the results of controller synthesis with
musyn by changing certain computation options.
The measure of robust performance calculated by
musyn is the μ upper bound.
musyn command synthesizes robust controllers using an
algorithm that includes iterating between optimizing robust performance (the
D step) and computing an H∞
controller (the K step).
