Conference Object Citation - Scopus: 1Robust Adaptive Control of Nonlinear Systems With Unknown State Delay(Institute of Electrical and Electronics Engineers Inc., 2013) Bayrak, Alper; Tatlıcıoğlu, Enver; Bıdıklı, Barış; Zergeroğlu, ErkanIn this work, we propose a new robust adaptive controller for a class of multi-input multi-output nonlinear systems subject to uncertain state delay. The proposed method is proven to yield semi-global asymptotic tracking despite the presence of additive input and output disturbances and parametric uncertainty in the system dynamics. An adaptive desired system compensation in conjunction with a continuous nonlinear integral feedback component is utilized in the design of the controller and Lyapunov-based techniques, are used to prove that the tracking error is asymptotically driven to zero. Numerical simulation results are presented to demonstrate the effectiveness of the proposed method. © 2013 IEEE.Conference Object Citation - WoS: 5Citation - Scopus: 6Set-Point Navigation of a Redundant Robot in Uncertain Environments Using Finite Range Sensors(Institute of Electrical and Electronics Engineers Inc., 2008) Kapadia, Apoorva; Tatlıcıoğlu, Enver; Dawson, Darren M.In this work, control of redundant robot manipulators in an uncertain environment is considered. The manipulator is equipped with finite range sensors to detect obstacles in its workspace. A navigation functionbased kinematic controller is proposed to ensure the regulation of the end-effector to a desired set-point while the entire manipulator simultaneously avoids the obstacle points detected by the sensors. A joint-space controller is then utilized to ensure asymptotic tracking of the desired jointspace trajectory.
