Abstract: PROBLEM TO BE SOLVED: To provide a system for improving accuracy of estimated parameters that may be important for control during fast transient events, where reduced accuracy of the parameters may lead to poor controllability and poor balance between performance and life objectives.SOLUTION: A controller includes processors that receive a first set of inputs. The processors also generate a first set of modeled outputs of a power generation system on the basis of a model of the system and of the first set of inputs. The processors further receive a first set of measured outputs corresponding to the first set of modeled outputs. The processors determine a first correction factor on the basis of the first set of modeled outputs and the first set of measured outputs. The first correction factor includes differences between the first set of modeled outputs and the first set of measured outputs. The processors also generate a second set of modeled outputs on the basis of the model, a second set of inputs, and the first correction factor, and control an operation of the power generation system on the basis of the second set of modeled outputs.SELECTED DRAWING: Figure 2
