Error Analysis in Unbiased FIR Filtering with Time-Stamped Discretely Delayed and Missing Data
Authors: , ,
Abstract: This investigation is motivated by communication effects such as delays and information loss in control loops on data travelling along wireless channels. The state-space model with k-step-lags in observations is transformed to have no latency and expanded on a finite horizon of N most recent data points. An analysis of error is provided for a novel unbiased finite impulse response (UFIR) filtering algorithm developed for discrete-time statespace models with time-stamped discretely delayed and missing data. A comparative analysis with the standard Kalman filter (KF) and robust H1 filter is also provided. It is shown that the UFIR filter is more robust than the KF and H∞ filter under the communication delays and missing data. The results are obtained by simulation and verified experimentally.
