Recurrent neural network based optimal integral sliding mode tracking control for four‐wheel independently driven robots

open access: yesIET Control Theory & Applications, 2021
This paper investigates robust path tracking issue of the four‐wheel independent driven robot (FWIDR) under time‐varying system uncertainties and unavoidable external disturbances.

Sensitivity Minimisation for the Class of Self-Tuning Control Systems

open access: yes, 1995
A new method for designing self-tuning control systems is proposed. The ultimate goal of the presented approach is to construct a self-tuner capable of coping with situations when the process under control cannot be modelled accurately within the ...

Adaptive fuzzy fault‐tolerant control of seat active suspension systems with actuator fault

open access: yesIET Control Theory & Applications, 2021
This paper proposes an adaptive fuzzy fault‐tolerant control method about seat active suspension systems. The significant indexes of seat active suspension system are ride comfort and safety.

An introduction to event-triggered and self-triggered control

open access: yes, 2012
Recent developments in computer and communication technologies have led to a new type of large-scale resource-constrained wireless embedded control systems. It is desirable in these systems to limit the sensor and control computation and/or communication

Intelligent control of a single‐link flexible manipulator using sliding modes and artificial neural networks

open access: yesElectronics Letters, 2021
This letter presents a new intelligent control scheme for the accurate trajectory tracking of flexible link manipulators. The proposed approach is mainly based on a sliding mode controller for underactuated systems with an embedded artificial neural ...

Model‐free linear active disturbance rejection output feedback control for electro‐hydraulic proportional system with unknown dead‐zone

open access: yesIET Control Theory & Applications, 2021
Here, a model‐free linear active disturbance rejection controller (LADRC) integrating dead‐zone inverse compensation for an electro‐hydraulic proportional (EHP) system with an unknown dead‐zone is proposed.

Self-repair ability of evolved self-assembling systems in cellular automata [PDF]

open access: yes, 2014
Self-repairing systems are those that are able to reconfigure themselves following disruptions to bring them back into a defined normal state. In this paper we explore the self-repair ability of some cellular automata-like systems, which differ from ...

Adaptive event‐triggered control of multi‐agent systems with state constraints and unknown disturbances

open access: yesIET Control Theory & Applications, 2021
The leader‐following consensus problem of a class of non‐strict feedback multi‐agent systems with unknown disturbances, this paper develops a novel adaptive event‐triggered control strategy ground on the consideration of the full state constraints ...

Adaptation to the edge of chaos in the self-adjusting logistic map. [PDF]

open access: yesPhysical Review Letters, 2000
Self-adjusting, or adaptive, systems have gathered much recent interest. We present a model for self-adjusting systems which treats the control parameters of the system as slowly varying, rather than constant. The dynamics of these parameters is governed

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
