146 CHAPTER 4. DEMONSTRATION EXAMPLES
g3 = starp(himat ic,k3)
g3g = freq(g3,omega)
[bnds3,D3,D3inv,Delta3,sens3] = mu(g3g,blk)
At this point we could do another iteration (to get k4) or perhaps run some simulations
to check out k3 more thoroughly.
4.1.8 Simulation Comparison with a Loopshaping Controller
A loopshaping design is performed and compared to the H∞and µdesigns. As the
loopshaping design procedure is relatively standard, only the final controller is given
here (klp).
