Summary on Grant Application Form |
|
The project will Provide a method for identifying nonlinear systems from their responses to perturbation signals. Models of the systems will be determined in the form of hierarchies of generalized frequency response functions. The initial work will be directed to obtaining relationships between these functions and the harmonics of the system input and output signals in a form that can provide the basis for an identification methods. The complexity of these relationships will be reduced by using periodic multi-frequency perturbation signals with sparse harmonics as the system inputs, and by spectral decomposition of the system outputs. The use of other kinds of perturbation signals will be considered when the basis of the identification method has been established. The effects of higher-order generalized frequency response functions on the accuracy of the estimates of lower-order functions will also be investigated. The method will be tested on appropriate processes in the steel industry.
