Compensating for noise and perturbances in linear object control

We consider the problem of constructing a robust control system for a linear stationary object under unmeasurable perturbances acting on the object. The perturbances are unbounded on the input of the system and bounded on the output. Based on the system inclusion technique, we consider necessary and sufficient conditions for the linear stationary systems' invariance to perturbances. With the auxiliary contour method, we compensate for the undesirable effects of perturbances on controlled variables. We give an illustrative example and computer modeling results.
