Beschreibung
Zusammenfassung:	This invention relates to the control systems for the complex technical objects operating in wide range of modes and loads and can be used in the control systems of gas turbine engines, turbines of electrical power generating stations etc. According to the method the sensors (3) are connected with state observers established on the base of engine (object) (1) model, one observer being connected with all sensors and each of remain observers with all sensors except one, the weighted sum of squared residuals of all observers is determined, the value of weighted sum of squared residuals of the first observer is compared with the values of weighted sums of squared residuals of the each observer from the remain ones, the maximum of received difference signal values is compared with threshold value and the failure signal is established for that sensor (3) indications of which are not used in observer for which this value exceeds the threshold, for each state observer is determined the region of possible residual locations, caused by the errors of predetermined parameters of object model, and it is defined that state observers the residuals of which are outside the limits of predetermined region.
