Abstract: The paper describes a condition-monitoring scheme based on first principles models the scheme involves estimating the values of model parameters that are expected to change in the event of a fault. The first principles models are, in general, not linear in the parameters, and recursive estimation of the parameters of these models is avoided by estimating the parameters of an intermediate model that is linear in the parameters. This intermediate model, which takes the form of a radial basis function network, is used periodically to generate data covering the complete operating range of the system. These data are then used in the estimation of the parameters of the first principles model. The paper describes the techniques used and presents results from applying the method to the task of detecting two faults in the cooling coil subsystem of an air-handling unit.
