| Abstract: | Aiming at the constraints of the extended kalman filter(EKF),the poor dynamic tracking and degradation ability of the particle filter algorithm,and the low precision of the single unscented kalman filter(UKF),an unscented kalman fault estimation filter with limited memory method was designed based on maximum a posterior(MAP) estimation.Firstly,an optimal MAP-UKF multiplicative fault estimator is derived according to MAP estimation.Then,the sub-optimal actuator fault estimation filter algorithm is derived.Me... |
