A measurement adaptive Huber filter and application in circuit system
Chu Rui · 2011
Amine at the non-optimal state estimation problem of a circuit system with the measurement noise being uncertain,a Huber-based adaptive filter is proposed,which recasts the measurement update step into a linear regression problem,thus,the optimal estimation of the circuit system can be obtained by an iterative solution of the measurement residual.Simulation results show that,the proposed algorithm is of higher estimation accuracy than the traditional ones.
