In this paper, an integral sliding mode based tracking control (ISMTC) scheme is proposed for a marine surface vehicle (MSV) in order to achieve accurate tracking performance. Salient features of the ISMTC scheme are as follows: (1) The integral sliding mode (ISM) technique is employed to realize accurate tracking performance, whereby a finite-time unknown observer is designed and integrated into...
In this paper, a finite-time disturbance observer based non-singular integral terminal sliding mode tracking control scheme for trajectory tracking of an unmanned surface vehicle (USV) is proposed. The salient features of the proposed scheme are as follows: 1) The proposed control scheme contributes to precise trajectory tracking control of an USV. 2) Under the proposed control law, tracking errors...
In this paper, a global finite-time tracking control (GFTC) scheme is proposed for trajectory tracking control of an autonomous surface vehicle (ASV). The salient features of the GFTC scheme are triple fold: 1) A discontinuous controller is developed to realize the finite-time stability of the closed-loop ASV trajectory tracking system. 2) The GFTC scheme can render tracking errors converge to zero...
For homing missiles considering terminal angular constraint, integrated design of guidance and control utilizing adaptive command filtered backstepping is studied in this paper. The proposed control scheme guarantees not only the stability of the missile dynamics with state constraints but also the interception performance with a desired terminal attitude angle. An adaptive law is introduced to compensate...
In this paper, a finite-time trajectory tracking control approach is proposed for an unmanned surface vehicle (USV) with unknown external disturbances and input saturation. Significant contributions of this paper are as follows: 1) an auxiliary design system is employed to address input constraint effectively, and make sure control performance ideally; 2) an disturbance observer is designed via a...
This paper addresses the finite-time trajectory tracking control problem of an unmanned surface vehicle with external disturbances. The salient features of the proposed control scheme are as follows: 1) A disturbance observer is designed firstly such that the external disturbances can be exactly observed in a finite time; 2) A disturbance observer based nonsingular terminal sliding mode control law...
