This paper aims to provide a low-level control strategy for a robot represented by a nonlinear second-order dynamics to avoid collision while tracking a specified trajectory in a dynamic environment and to extend it to coordinated trajectory tracking and collision-avoidance. Back-stepping technique has been exploited for trajectory tracking and collision-avoidance is performed by a repulsion function...
The Letter introduces a robust control design method to synchronize a pair of different uncertain chaotic systems. The technique is based on sliding-mode and variable structure control theories. Comparison of proposed method with previous works is performed during simulations. It is shown that the proposed controller while appearing in a faster response, is able to overcome random uncertainties of...
