Overview on m Synthesis
qConsider a general feedback system with interconnection G. Find a stabilizing controller K so that the following m-norm is minimized:
This problem is called m-synthesis.
qThe m-synthesis is not yet fully solved. But a reasonable
approach is to “solve”
by
iteratively solving for K and D, i.e., first minimizing over K with D fixed, then minimizing
point-wise over D with K fixed, then again over K, and again over D, etc. This is the
so-called D-K Iteration.
