is that anyone is good in solve this convex optimization problem
where the v is the virtual reference signal and r is the reference input, at this case we can consider the r(t) as the step input.
For the O_infinity is the Maximal Output Admissible Set (MAS)=〖CA〗^j+〖(C(I-A〗^j)〖(I - A)〗^(-1) B + D <=s; where s is the maximum output.
