Abstract
PURPOSE:To make it possible to cope with a secular change and operation condition change by correcting the parameter of a model into a newly found parameter within the allowable range of parameter variation. CONSTITUTION:Difference (e) between output (y) of element 1 and output ym of model 2 and allowable value e0 are inputted to comparing circuit 3, which when ¦e¦>e0, decides on abnormality to send its output signal to abnormality deciding circuit 9. Input and output signals (u) and (y) of element 1, on the other hand, are inputted to parameter calculating circuit 4, which calculates the parameter of the transfer function of element 1. In view of the parameter, operation conditions, secular change of the element, etc., parameter abnormality deciding circuit 5 calculates the difference from a calculated and set reference parameter and outputs it to abnormality deciding circuit 9. When the parameter value calculated by parameter calculating circuit 4 is normal, the parameter is used as the parameter of model 2, so that it will be made invariably possible to cope with the characteristic change of the element that appears regardless of the normal state.
