Abstract :
A method for detecting and estimating the value of sudden bias shifts in a U-tube steam generator water level controller is described and evaluated. Generalized likelihood ratios (GLR) are used to perform both the bias detection and bias estimation. Simulation results using a seventh-order, linear, discrete steam generator model demonstrate the capabilities of the GLR detection/estimation approach.
