I have a problem with my H-Infity controller. I run the code but I get the error that the matrix is badly scaled and close to singular.
% sys_rock % Number of measurements nmeas = 2; % Number of controls ncon = 1; % lower bound of bisection gmin = 0.15; % Upper bound of bisection gmax = 1000000000; hin_ic = sel(sys_ic,8:11,8:11); tol = 0.00001; % hinfsyn command is used to compute the H-Infinty controller [K_hin,clp] = hinfsyn(hin_ic,nmeas,ncon,gmin,gmax,tol); disp(' ') minfo(K_hin)
I dont get how this produces a gamma value of 984192557.2224. It should be like 400000. Also i dont know why gmax should be so high. When i put it lower i get the error that it is too low.
I hope some one can give me a hint.
