In this article a fast, non-asymptotic algebraic method is used for the es timation of state variables. The estimation is used to implement a position control scheme for DC motor. In addition the estimation of the Coulomb's friction coeffi cient of the servo motor model has been investigated. The approach is based on el ementary algebraic manipulation that lead to specific formulae for the unmeasured states. The state estimation algorithm have been verified by simulation
