| Summary: | This paper is concerned with the problem of designing disturbance observer for fractional order systems, of
which the disturbance is in time series expansion. The stability of a special observer with the selected nonlinear weighted
function and transient dynamics function is rigorously analyzed for slowly varying disturbance. In addition, the result is
also extended to estimate slope forms disturbance and higher order disturbance of fractional order systems. The efficacy
of the proposed method is validated through numerical examples. |
