Patent ID: 8560283

Claim:
A method to compensate a first-principle based simulation model, comprising: applying one or more first test inputs to a process system to generate first output data; applying one or more second test inputs to a first principle model to generate second output data; determining a first prediction equation to express a relationship between the first test inputs and the first output data; determining an initial condition of the first prediction equation for one or more model parameters based on the first test inputs and the first output data; determining a second prediction equation for a first time based on at least one of a third prediction equation for a second time prior to the first time or the initial condition; generating an error model based on the first and second output data and based on at least one of the second or third prediction equations; applying model input data to the first principle model to generate simulation model output data; and compensating the simulation model output data via the error model to generate compensated model output data.
