Abstract
This paper considers robust reduced order H-infinity observer-based control for stochastic systems. The proposed approach is divided into two steps. First, we search for a linear control law to ensure H-infinity specification. Then, the obtained linear combination of the state is used to solve an unbiasedness (decoupling) condition on the drift part of the closed-loop system. Finally, deterministic functional filtering techniques are applied to obtain the observer-based controller.
