| Abstract: | The robust steady-state tracking problem subjected to coprime factor perturbations and unknown external bounded disturbance is addressed. An exact formula for computing the worst-possible steady-state absolute value of the control error is proposed by using Youla parameterization. With this formula, it is shown that the design of optimal robust steady-state tracking controller is reduced to l1 optimal robust controller design ensuring robust stability. |
