The finite/fixed-time stabilization and tracking control is currently a hot field in various
systems since the faster convergence can be obtained. By contrast to the asymptotic …

The science objectives of a spacecraft mission place stringent performance requirements on
the spacecraft attitude control system. However, it remains an open problem how to …

This study focuses on the design of a fixed-time disturbance observer-based robust fault-
tolerant tracking control scheme for an uncertain quadrotor unmanned aerial vehicle (UAV) …

This paper designs an active fault-tolerant control system for spacecraft attitude control in the
presence of actuator faults, fault estimation errors, and control input constraints. The …

In this article, a dynamic event-triggered control scheme for a class of stochastic nonlinear
systems with unknown input saturation and partially unmeasured states is presented. First, a …

This paper addresses the problem of adaptive fixed-time attitude stabilization for uncertain
rigid spacecraft with inertia uncertainties, external disturbances, actuator saturations, and …

This paper is concerned with the adaptive sliding mode control problem of uncertain
nonlinear systems. Interval type-2 Takagi-Sugeno (TS) fuzzy model is employed to represent …

In this paper, an adaptive sliding mode control system using a double loop recurrent neural
network (DLRNN) structure is proposed for a class of nonlinear dynamic systems. A new …

This paper investigates the problem of event-triggered adaptive control for a class of
