Time-Domain Identification of Dynamic Errors-in-Variables Systems using Period Excitation Signals
1999 (English)In: Proceedings of the 14th IFAC World Congress, 1999, 421-426 p.Conference paper (Refereed)
The use of periodic excitation signals in identification experiments is advocated. With periodic excitation it is possible to separate the driving signals and the disturbances, which for instance implies that the noise properties can be independently estimated. In the paper a non-parametric noise model, estimated directly from the measured data, is used in a compensation strategy applicable to both least squares and total least squares estimation. The resulting least squares and total least squares methods are applicable in the errors-in-variables situation and give consistent estimates regardless of the noise. The feasibility of the idea is illustrated in a simulation study.
