Operator failures in controlled systems can reduce their operation, cause instability and even cause dangerous casualties and accidents. Flaw causes structural changes and parametric uncertainties in the control system, which requires a new modeling for the control system as well as new control methods. The design of the control is applied to the dynamic model in the presence of a defect in the radar, ellerron and motor operators. The intended damage for these operators is considered to be "locked in place", that is, after the defect, the control levels remain uncertain and constant. In this paper, we examine several different control methods for controlling the operation of operators in the presence of uncertainty.
