The technique of μ synthesis
extends the methods of H∞
synthesis to design a robust controller for a SISO or MIMO 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.
- 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.
- Improve Results of Mu Synthesis
You can sometimes improve the results of controller synthesis with
musynby changing certain computation options.
- Robust Performance Measure for Mu Synthesis
The measure of robust performance calculated by
musynperfand optimized by
musynis the μ upper bound.
- D-K Iteration Process
musyncommand synthesizes robust controllers using an algorithm that includes iterating between optimizing robust performance (the D step) and computing an H∞ controller (the K step).
