Computer-based reconfiguration method for compensation of sensor failures within a sensor system to increase the failure tolerance of a measurement system by initialization of new observers when a failure condition is noted
Computer-based reconfiguration method for compensation of sensor failures within a sensor system to increase the failure tolerance of a measurement system by initialization of new observers when a failure condition is noted
Method is based on a system model (4) that models an application system (11) using system values (12) measured using sensors of a sensor system (1). The system model has a number of observers (6) for estimating the system values that are used by a data processing system (14). The latter detects a failure condition for an observer by comparison of the number of errors detected by a sensor with those estimated by a system model. When a failure state is detected by an observer (combination of a sensor and a system model) a further observer is initialized.
