TL;DR: A finite-time attitude tracking control scheme is proposed for spacecraft using terminal sliding mode and Chebyshev neural network (NN) (CNN) and the four-parameter representations are used to describe the spacecraft attitude for global representation without singularities.

TL;DR: A controller is proposed for the robust backstepping control of a class of nonlinear pure-feedback systems using fuzzy logic to learn the behavior of the unknown plant dynamics, and the uniform ultimate boundedness of all signals in the closed-loop system can be guaranteed.

TL;DR: This paper investigates the tracking control of an electrically driven nonholonomic mobile robot with model uncertainties in the robot kinematics, the robot dynamics, and the wheel actuator dynamics with a robust adaptive controller proposed with the utilization of adaptive control, backstepping and fuzzy logic techniques.

TL;DR: A rigorous proof shows that semi-global finite-time stability of the overall closed-loop system can be achieved and the proposed velocity-free control law guarantees a group of spacecraft to simultaneously track a common time-varying reference attitude in finite time even when the reference attitude is available only to a subset of the group members.

TL;DR: Rigorous proof shows that the proposed control law ensures semiglobal stability and guarantees the attitude of a rigid spacecraft to track a time-varying reference attitude in finite time.
