This paper presents an adaptive constrained attitude control for uncertain spacecraft. Inspired by the concept of nonsingular terminal sliding mode and funnel nonlinear systems, a novel is introduced which contains time-varying gain to handle constraints imposed on spacecraft attitude. Indeed, when trajectory approaches boundary constraint set, effort as well will increase in order preclude fro...

The bridge crane system is a typical under-actuated that widely used in production and life. Although various scholars have conducted extensive research on the recent years, there are still many problems, such as trajectory planning of cart anti-sway control cargo. In order to tackle problem cargo, hierarchical global fast terminal sliding-mode (H-GFTSMC) developed this work. First, Lagrange eq...

This study investigates the speed control of permanent magnet synchronous motors in presence external load disturbances via fast terminal sliding-mode (FTSMC). First, to enhance tracking performance, a logarithmic FTSMC method based on novel sliding surface is proposed improve previously introduced FTSMC. Second, we have derived an enhanced settling time, demonstrating its superiority over that...

A blended autopilot algorithm is developed using generalized predictive control and adaptive non-singular terminal sliding mode control, for dual control missile steered by combination of aerodynamic fins and reaction jets. The blended algorithm considers the reaction jets control design prior due to its inherent control error, and then treats the aerodynamic fin control on the basis of the rea...
