Hello,
I have four state space matrices A,B, C and D. I need to use the 'hinf' command in matlab to get the controller transfer function in this form: K(z) = 0.02367z4 + 0.0003702z3 − 0.01514z2 + 0.007138z − 0.001015/z4 + 2.811z3 + 3.268z2 + 1.918z + 0.4738
I do not understand how to use Hinf to make my plant P and get to K(z). i need the k(z) equation as given above but i cant get past mksys(A,B,C,D,'tss') which gives me a long weird number. I think i am going wrong, i thought mksys would give me the plant P. can i get some direction, i am totally lost and new to control theoretic approaches in matlab.
Thanks!
