The task of ensuring the guaranteed accuracy of the synthesized system of automatic control of the actions of undefined random disturbances on it is considered. The formation procedure and features of the structure of the control system of guaranteed accuracy are shown, which, when compensating for disturbances, ensures the preservation of control quality (system stability and the quality of the transient process). The proposed method of forming a corrective influence to compensate for the action of disturbances as a function of the approximation of the system state variable to the limit of its permissible value.
