Device and method for residual evaluation of a residual for detecting system errors in the system behavior of a system of an aircraft

摘要

Device (E) for residual evaluation of a residual (r) for the detection of system errors in a system (S), which receives a time-variable reference variable (w) and a disturbance variable (z) representing external disturbances on the input side and provides a system output variable (y) on the output side , with: a) a device (V) for generating the residual (r) at least as a function of the reference variable (w) and the system output variable (y); b) a comparator unit (KE) for providing an evaluation result (b) by means of a comparison of the residual (r) with a threshold value (s) provided; c) a first unit (E1) for providing a constant threshold value component (s0); d) a second unit (E2) for providing an adaptive threshold value component (s1) at least as a function of the time-variable reference variable (w); and e) a third (s) by linking the constant threshold value component (s0) with the adaptive threshold value component (s1).
