Sliding mode disturbance observer and sliding mode controller for quadrotor UAV

open access: yesJournal of Physics: Conference Series, 2022
Abstract The dynamics of quadrotor UAV is described considering internal uncertainty and external disturbance. The control system of quadrotor UAV is divided into inner loop attitude control system and outer loop position control system, In order to solve the problem of underactuated character.

Decentralised sliding mode control for a class of nonlinear interconnected systems [PDF]

open access: yes, 2015
In this paper, a decentralised control strategy based on sliding mode techniques is proposed for a class of nonlinear interconnected systems. Both matched uncertainties in the isolated subsystems and mismatched uncertainties associated with the ...

ON DISCRETE-TIME SLIDING MODES

open access: yesIFAC Proceedings Volumes, 1989
Abstract In the paper the problems of sliding modes simulation and sliding mode digital control design are considered. The simulation problem of the dynamic systems with discontinuous right-hand side is a nontraditional one. The principle difficulty is in the fact that in such systems there is a special kind of motions - sliding modes.
