Comments on "modified extended Kalman filtering and a real-time parallel algorithm for system parameter identification"

In the above said paper by Chui et al. ( ibid. vol.35, no.1, p.100-4 (1990)), a modification of the extended Kalman filter algorithm (MEKF) is introduced and illustrative examples are presented. In this note, we point out that the examples demonstrating the advantage of the MEKF over the conventional EKF are inappropriate.<
