Small bodies have the characteristics of noncooperative, irregular gravity, and complex terrain on the surface, which cause difficulties in successful landing for conventional landers. In this paper, a multinode flexible lander is put forward to addr

This paper proposes an electric propulsion platform based on a triple orthogonal gimbaled thruster boom to realize the GTO-GEO transfer process. The adjustment mechanism of the gimbaled thruster boom significantly improves the range of thrust vector

A predefined-time attitude controller for electric spacecraft and its thrust booms is investigated by combining a second-order sliding mode control with predefined-time disturbance observer. First, an Eulerian–Lagrangian attitude dynamics model of

This paper addresses the problem of six-degree-of-freedom (6-DOF) relative position and attitude-tracking control for noncooperative space targets subject to multiple constraints, including input and full-state constraints. First, a novel 6-DOF integ

An active crowbar protective circuit is an effective and common approach for low voltage ride through (LVRT) of a doubly-fed induction generator (DFIG). The crowbar resistance value and its switching scheme both have crucial effects on safety recover

In this paper, the attitude tracking control problem of hypersonic reentry vehicles is addressed by synthesizing a neural network (NN) using the backstepping control technique. The control-oriented model is formulated with mismatched and matched lump
