19 Oct 2011 Minimum settling time control design through direct search optimization methods New approach for designing controllers explicitely minimizing the settling time of a time response. Author: Emile Simon

For more details about restarting Nelder-Mead (e.g. fminsearch) to improve its convergence, see the description and file on http://www.mathworks.com/matlabcentral/fileexchange/33328

13 Oct 2011 A direct search method instead of a coordinate descent iterative LMI algorithm Illustrates on an example the efficiency of using a direct search method (instead of an ILMI). Author: Emile Simon

Second version available, heavily commented.
See the short preprint on http://arxiv.org/abs/1110.2615 for important points.

See the different preprint on http://arxiv.org/abs/1104.5183 for some other experiment results.
12 Oct 2011 A direct search method instead of a coordinate descent iterative LMI algorithm Illustrates on an example the efficiency of using a direct search method (instead of an ILMI). Author: Emile Simon

The first version of this program has a small implementation problem. The second version will be available shortly, with more comments.
06 Oct 2011 The Optimal ITAE Transfer Function for Step Input Revisit the optimal ITAE transfer function using numerical optimization and digital computer Author: Yi Cao

Note that the same results are achieved by using fminsearch instead of fminunc in itaeoptimtf. fminsearch is the Matlab implementation of the Nelder-Mead algorithm (1965), a direct search method not using gradient information. This indicates that DS methods are adequate for time response shaping problems, and i used this for settling time minimization (for which gradients are not available and fminunc will fail at using finite differencing derivative estimations), see files #33022.
