fmincon_fun.m

国外专家做的求解LMI鲁棒控制的工具箱,可以相对高效的解决LMI问题

function f = fmincon_fun(x,dummy1,dummy2,dummy4)

persistent interfacedata
persistent monomtable
persistent nonlinearindicies
persistent linearindicies
persistent xx
if nargin == 4
    interfacedata = dummy4;
    monomtable = interfacedata.monomtable;
    nonlinearindicies = interfacedata.nonlinearindicies;
    linearindicies = interfacedata.linearindicies;
    xx=ones(1,size(interfacedata.monomtable,2));     
    return
end

xx(linearindicies) = x(:)';

for i = 1:length(nonlinearindicies)
    xx(nonlinearindicies(i)) = prod(xx.^monomtable(nonlinearindicies(i),:));
end

f = interfacedata.c'*xx(:)+xx(:)'*interfacedata.Q*xx(:);
