INTEGRAL-EQUATION APPROACH TO PARAMETER-IDENTIFICATION WITHOUT CONSIDERATION OF INITIAL CONDITIONS

The widely used integral-equation approach for identification of conti nuous systems is investigated. Attention is focused on the initial con dition problem which has been puzzling many researchers. A new calcula tion procedure for the multiple integrations of the system signal deri vatives is proposed and a new integral-equation approach is proposed f or which the initial conditions need not be identified as unknown para meters. Therefore, the burden of the identification algorithms can be greatly reduced compared to conventional methods. Discussions on the u nification of the integral-equation approach with the other methods ar e also provided.
