Research ArticleOpen accessIn the abstractRehabilitation of a Human Arm Supported by a Robotic Manipulator: A Position/Force Cooperative ControlHaifa Mehdi, Olfa BoubakerProblem statement: The assistance of person with limited ability of arm movement is necessary for rehabilitation reasons. This aid is required not only to cover the human performances of the arm in motion and force but also to have a strictly stable dynamics. In this study, we proposed a cooperative system between a disabled arm and a robotic manipulator to … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Distributed Control System Using a Personal Computer and Micro Control Units for Humanoid RobotsMitsuhiro Yamano, Akihiro Ochiai, Yuichi Suzukawa et al.Problem statement: Humanoid robots have many motors and sensors and many control methods are used to carry out complicated tasks of the robots. Therefore, efficient control systems are required for the robots. Approach: This study presented a distributed control system using a Personal Computer (PC) and Micro Control Units (MCUs) for humanoid robots. Distributed control systems have the advantages that … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Controller Design of an Electro-Hydraulic Actuator SystemM. F. Rahmat, S. Md. Rozali, N. Abdul Wahab et al.Problem statement: Electro-hydraulic actuators are widely used in motion control application. Its valve needs to be controlled to determine direction of the motion. Mathematical modeling is a description of a system in terms of equations. It can be divided into two parts; physical modeling and system identification. The objective of this study was to obtain mathematical model of an electro-hydraulic … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 11,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Fuzzy Logic Control with Input Shaping for Input Tracking and Sway Suppression of a Gantry Crane SystemM. A. Ahmad, Z. MohamedProblem statement: Most of the common gantry crane results in a sway motion when transporting the load as fast as possible. In addition, precise cart position control of gantry crane must required a zero or near zero residual sway. Approach: In this study, the development of hybrid control schemes for input tracking and anti-sway control of a gantry crane system … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal Time Implementation of NARMA-L2 Control of a Single Link ManipulatorS.S. Mokri, H. Husain, W. Martono, A. ShafieNonlinearities and parametric uncertainties are unavoidable problems faced in controlling robot manipulator. A single link manipulator driven by a permanent magnet brushed dc motor is a nonlinear dynamics due to effects of gravitational force, mass of the payload, posture of the manipulator and viscous friction coefficient. Furthermore, uncertainties arise because of changes of the rotor resistance with temperature and random … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,761 accessesView PDFCite
