In the present paper a study on the sensitivity functions in electro-mechanical systems is introduced. This study takes into account the effect of parameters variation of the controlled plant. Also, the effect of the unmeasurable disturbance are studied. The possibility of identifying the unstationary parameters of an electro-mechanical system is viewed, using the suitable adaptive control law. A new algorithm for designing an adaptive observer is introduced. The designed observer insures the possibility of evaluating the transfer co-efficient of the controlled electro-mechanical plant, under the effect of unmeasurable disturbances on the load side. The suggested adaptive observer helps in stabilizing the dynamic behavior of electro-mechanical systems.
