Please add mu syntesis

[Uwe Fechner]

The technique of μ synthesis extends the methods of H∞ synthesis to design a robust controller for an uncertain plant.
musyn seeks a controller that minimizes the robust H∞ performance of the closed-loop system. The robust H∞ performance, also called μ, quantifies how modeled uncertainty affects the performance of a feedback loop.

How to calculate the robust Hinfinity performace µ is described here: https://nl.mathworks.com/help/robust/ug/measures-of-robust-performance.html

I will not be implementing this method, I encourage you to implement it if you find it useful for your work :)
