Controller settings search area determination in the condition of reduced sensitivity to control object parameters drift

A definition method for the area of controller admissible parameters set-up in an aircraft, machine-building and other industries is offered in this article. Admissible adjustments areas of controller parameters are defined, at which closed control systems have smaller sensitivity to possible deviations of object parameters regulation during their operation. The examples of method applied to automatic control systems of vacuum in the furnace and drum-type boiler flow rate controller are considered.
