Extended Kalman Filtering (EKF) is proposed for: (i) the extraction of a fuzzy model from numerical data; and (ii) localization an autonomous vehicle. In first case, EKF algorithm compared to Gauss–Newton nonlinear least-squares method shown be faster. An analysis convergence given. second estimates state vector vehicle by fusing data coming odometric sensors sonars. Simulation tests show that accuracy EKF-based satisfactory.

For nonlinear systems, subject to Gaussian noise, the extended Kalman filter (EKF) is frequently applied for estimating system's state vector from output measurements. The EFK based on linearization of systems' dynamics using a first-order Taylor expansion. Although EKF efficient in several problems, it characterized by cumulative errors due gradient-based performs, and this may affect accuracy estimation or even risk stability estimation-based control loop. To overcome flaws EKF, has been...

A control method for distributed interconnected power generation units is developed. The system comprises permanent-magnet synchronous generators (PMSGs), which are connected to each other through transformers and tie-lines. derivative-free nonlinear Kalman filtering approach introduced aiming at implementing sensorless of the generators. In proposed method, generator's model first subjected a linearization transformation that based on differential flatness theory next state estimation...

State estimation is a major problem in industrial systems, particularly robotics. To this end, Gaussian and nonparametric filters have been developed. In paper, the extended Kalman filter, which assumes measurement noise, compared with particle does not make any assumption on noise distribution. As case study, of state vector an robot used when measurements are available from accelerometer that was mounted end effector robotic manipulator encoders joints' motors. It shown that, kind sensor...
