This paper presents a time-varying disturbance-observer-(TVDO-) based improved sliding-
mode control (ISMC) method to achieve tracking control of uncertain flexible-joint …

In the present study, a predefined-time attitude stabilization for liquid-filled spacecraft with
large liquid sloshing is investigated under input saturation and external disturbance. First …

This paper mainly proposes a new disturbance observer (DO) for a secure communication
system (SCS) of the chaos-based system (CBS). First, the fractional-order (FO) Chen chaotic …

The present paper investigates a fixed-time tracking control with fractional-order dynamics
for a quadrotor subjected to external disturbances. After giving the formulation problem of a …

This paper proposed a new disturbance observer (DO) based on the fixed-time supper-
twisting algorithm (FTSTA) for rejecting perturbations of secure communication of the …

To prevent the loss of data or distortion of the real sent data in the secure communication,
the disturbance and uncertainty rejection is very important technique. Especially, the secure …

This paper proposes a fixed-time stability (FTS) disturbance observer based-on an adaptive
sliding mode control for the secure communication of chaos-based system. Firstly, the …

This paper proposes a new fixed-time disturbance observer (FTDOB) based on the fractional-
order state observer (FOSOB) and a super-twisting sliding-mode control (STSMC) for a …

To prevent the distortion of the data transmission, the disturbance compensation method is
highly required in the communication system. Therefore, the variations of parameters on …
