Journal ArticleDOI
Incremental fuzzy expert PID control
TL;DR: An approach to intelligent PID (proportional integral derivative) control of industrial systems which is based on the application of fuzzy logic is presented, and it is possible to determine small changes on these values during the system operation, and these lead to improved performance of the transient and steady behavior of the closed-loop system.
Journal ArticleDOI
Extended Kalman filtering for fuzzy modelling and multi-sensor fusion
TL;DR: Extended Kalman Filtering (EKF) as mentioned in this paper was proposed for the extraction of a fuzzy model from numerical data and the localization of an autonomous vehicle in the first case.
Book
Introduction to Mobile Robot Control
TL;DR: The book begins with a study of mobile robot drives and corresponding kinematic and dynamic models, and discusses the sensors used in mobile robotics, and examines a variety of model-based, model-free, and vision-based controllers with unified proof of their stabilization and tracking performance.
Journal ArticleDOI

TL;DR: The SENARIO project is develoing a sensor-aided intelligent navigation system that provides high-level navigational aid to users of powered wheelchairs and has succeeded in fully supporting semi-autonomous navigation.
Journal ArticleDOI
Feedback Control of an Omnidirectional Autonomous Platform for Mobile Service Robots
TL;DR: This paper proposes a feedback control scheme for an omnidirectional holonomic autonomous platform, which is equipped with three lateral orthogonal-wheel assemblies, and shows that full omniddirectionality can be achieved with decoupled rotational and translational motions.
