This paper investigates the robust H-infinity reduced order observer-based control. The control gain is designed using standard $\cHi$ techniques. This gain is then used to resolve unbiasedness condition on the estimation error. Finally, the observer matrices are derived through the computation of a unique gain by means of Linear Matrix Inequalities.
