The article considers the estimability of the deviations of actual output variable values from the forecast ones in the system for monitoring the process of external round grinding. The author proposes the method for determining the deviations and establishing their most probable values as well as for establishing the cause of such output variable value deviations and technological system changes. It is substantiated that the determination of the output variable deviations and the parameters of the technological system state is possible at the control of the output variable change rate as the interruption time intervals are different for different subsystems. The authors managed to determine the dependences of the deviations of actual values (t) from the estimated ones yр(t). To resolve the objective of identifying the causes of output value deviations from the forecast ones, the authors applied the method for determining the indirect measurement errors. The obtained dependences made the authors draw the conclusion that at the control of the change rate of output variable values one is able to find out the disturbance type and the type of the deviation of output variable actual values in the technical system. This provides for the opportunity to correct the control of the external round grinding process as well as to calculate the time intervals at which one needs to take into account some or other changes in the technological system.
