International Journal of Control, Automation, and Systems, vol. 16, no. 3, pp.1049-1059, 2018
Abstract : "This study presents fractional-order Kalman filers for linear fractional-order systems with colored noises
using Tustin generating function. A continuous-time fractional-order system with the fractional-order colored process
noise is discretized by Tustin generating function. The augmented vector consists of the state and the colored
noise is offered to construct an augmented system based on the discretized state equation of a fractional-order system
and the colored process noise. The Tustin fractional-order Kalman filter is designed based on the augmented
system to obtain the state estimation, effectively. Besides, the colored noise involved in the measurement of a
continuous-time fractional-order system is also discussed, and the corresponding Tustin fractional-order Kalman
filter is provided in this study. Two illustrative examples are given to verify the effectiveness of Tustin fractionalorder
Kalman filters for the colored process and measurement noises.d separately by solving a set of LMIs and then used to estimate the unmeasured states, sensor and actuator"
