In this paper, an adaptive output feedback tracking control scheme is proposed for spacecraft formation flying (SFF) in the presence of external disturbances, uncertain system parameters, input constraints and partial loss of control effectiveness. The proposed controller incorporates a pseudo-velocity filter to account for the unmeasured relative velocity, and the neural network (NN) technique is...
The high precision of a piezo-electric positioning stage almost depends on whether the designed controller can effectively compensate the inherent hysteresis phenomenon. In this paper, an adaptive output feedback controller based on a radial basis function neural network (RBFNN) is proposed to eliminate the tracking errors caused by the hysteresis behavior. The observer-based RBFNN is used to online...
An adaptive output feedback controller based on neural network (NN) is proposed, which forces a surface ship at high speed to track a desired path. In general, tracking problem of the surface ship at low speed has been widely investigated in many studies, in which coupling interactions among the forces from each degree of freedom (DOF) is not considered. Nevertheless, the nonlinear characteristics...
