 **Limitation**: Using automated design tools for robust control of SISO systems has its benefits outweighed by the labor involved in creating the weighting transfer functions [@atsumiModifiedBodePlots2012]. 
 There is some work going on that tries to deal with this @atsumiModifiedBodePlots2012 . These people have made a tool that can create transfer functions using an upper bound of $\Delta$ and $W$ 
 
-**Limitation**: Disk unstructured uncertainty cannot lend itself to creating individual examples of perturbed plants. It is not as simple as picking a plant that is within the robust control disk, because the transfer function that actually gets you there is lost in the abstraction. Or perhaps generalized.
