This paper develops a general and implementation friendly stability framework for self-learning control (SLC) laws of the form $u(t)=k_1(t)u(t-\tau)+k_2 v(t)$. Uniform ultimate boundedness is established for a class of general linear plants under two engineering actuator assumptions: (i) smoothness and (ii) saturation with maximum value. These assumptions are reasonable for practical systems and yield an explicit bound, which converts the delay learning mechanism into a nominal (delay-free) controller plus a bounded perturbation injection. The most notable feature of SLC is its simplicity of structure coupled with excellent performance. It is compatible with traditional algorithms and can e... More >

This study investigates the finite-time attitude tracking problem of spacecraft. We employ finite-time control methods to develop a novel adaptive controller. The controller utilizes a time-varying non-singular adaptive fast terminal sliding mode. The time-varying sliding mode dynamically adjusts the sliding surface morphology. This adjustment enables precise control performance tuning. Additionally, adaptive methods estimate the upper bound of generalized disturbances. This estimation reduces the computational load of the controller. The proposed controller demonstrates high robustness against external disturbances and inertia uncertainties. Lyapunov methods prove the stability of the contr... More >

Fixed-wing unmanned aerial vehicle (UAV) formation technology, as a crucial research direction in multi-agent system cooperative control, while facing constraints in multiple areas, has demonstrated broad application prospects in military reconnaissance, disaster monitoring, agricultural plant protection and other fields in recent years.
