Finite-time command filtered backstepping control for a class of nonlinear systems
Jinpeng Yu,Peng Shi,Lin Zhao +2 more
TL;DR: A novel finite-time command filtered backstepping approach is proposed by using the new virtual control signals and the modified error compensation signals, which not only has the advantages of the conventional command-filtered backstepped control, but also guarantees the finite- time convergent property.

Fixed-Time Attitude Control for Rigid Spacecraft With Actuator Saturation and Faults
TL;DR: This brief investigates the finite-time control problem associated with attitude stabilization of a rigid spacecraft subject to external disturbance, actuator faults, and input saturation and develops a novel fixed-time sliding mode surface, and the settling time of the defined surface is shown to be independent of the initial conditions of the system.

Fault tolerant finite-time leader-follower formation control for autonomous surface vessels with LOS range and angle constraints
TL;DR: It is shown that under the proposed control method, despite the presence of actuator faults and system uncertainties, the formation tracking errors can converge into arbitrarily small neighborhoods around zero in finite time, while the constraint requirements on the LOS range and angle will not be violated.

Quaternion-Based Hybrid Control for Robust Global Attitude Tracking
TL;DR: This work proposes a quaternion-based hybrid feedback scheme that solves the global attitude tracking problem in three scenarios: full state measurements, only measurements of attitude, and measurements of attitudes with angular velocity measurements corrupted by a constant bias.
