In this paper an optimal robust controller, in terms of structured singular value-μ minimizing is designed for spin stabilized seeker, for achieving proper robust stability and robust performance with respect to the multiplicative input diagonal uncertainty. This optimal robust control can be designed using DK-iteration. This optimality involves solving a sequence of scaled H problems. We do the DK-iteration up to 3, to show the number of iteration effects in stability and performance quality of the synthesized control systems. Finally, designed controllers are applied to the plant and simulation results in time and frequency domains such as; step response, external and process disturbances rejection, robust performance and scan performance are shown and compared for these controllers and some other works.
