Adaptive Discrete-Time Higher Order Sliding Mode
TLDR
A technique to design a DHOSM control with adaptive switching gains where the bound on the disturbance is considered to be unknown is presented.Abstract:
The concept of discrete-time higher order sliding mode (DHOSM) has received increased attention. However, because of the dearth of knowledge on bound of the external disturbance in the system, an adaptive control law is desirable. This brief presents a technique to design a DHOSM control with adaptive switching gains where the bound on the disturbance is considered to be unknown.read more

Adaptive–Robust Approach for Time-Delayed Control of a Class of Uncertain EL Systems
Spandan Roy,Indra Narayan Kar +1 more
TL;DR: The main feature of the proposed adaptive-robust time-delayed control (ARTDC) is that, compared to the state-of-the-art, it does not involve any threshold value in its ARC law; thus, it allows the switching gain to increase or decrease whenever the error trajectories move away or move close to the switching surface.

Sliding order and sliding accuracy in sliding mode control
TL;DR: It turns out that the deviation of the system from its prescribed constraints (sliding accuracy) is proportional to the switching time delay and a new class of sliding modes and algorithms is presented and the concept of sliding mode order is introduced.

New methodologies for adaptive sliding mode control
TL;DR: The goal is to obtain a robust sliding mode adaptive-gain control law with respect to uncertainties and perturbations without the knowledge of uncertainties/perturbations bound (only the boundness feature is known).

Discrete-time quasi-sliding-mode control strategies
TL;DR: A new definition describing the quasi-sliding mode as a motion of the system, such that its state always remains in a certain band around the sliding hyperplane, is introduced and two novel reaching laws satisfying conditions of the definition are proposed and applied to the design of appropriate linear control strategies.

A New Adaptive Sliding-Mode Control Scheme for Application to Robot Manipulators
TL;DR: A new adaptive sliding-mode control scheme that uses the time-delay estimation (TDE) technique, then applies the scheme to robot manipulators and shows that the tracking errors of the proposed ASMC scheme are guaranteed to be uniformly ultimately bounded (UUB) with arbitrarily small bound.
