A Bayesian Adaptive Unscented Kalman Filter for Aircraft Parameter and Noise Estimation

Figure 3

Comparison of the parameter estimation performance of the three algorithms. The algorithms are the Bayesian UKF (BUKF) which is proposed in this paper, the simplified UKF (SUKF) with prior noise knowledge, and the parallel UKF (PUKF) proposed in reference [5]: (a) estimation results of ; (b) estimation results of ; (c) estimation results of ; (d) estimation results of .
