Improved multiverse optimizer‐based anti‐saturation model free adaptive control and its application to manipulator grasping systems

IET Control Theory & Applications
To address the stable grasping control issue in manipulator grasping systems, this manuscript proposes an improved multiverse optimizer‐based anti‐saturation model‐free adaptive control (IMVO‐AS‐MFAC) algorithm.

Quantitative SPECT/CT imaging of actinium-225 for targeted alpha therapy of glioblastomas

EJNMMI Physics
A new, alternative option for patients with recurrent glioblastoma is targeted alpha therapy (TAT), in the form of a local administration of substance P (neurokinin type 1 receptor ligand, NK-1) labelled with 225Ac.

Modeling the effect of daughter migration on dosimetry estimates for unlabeled actinium-225.

Medical Physics (Lancaster)
BACKGROUND Actinium-225 (225 Ac) is an alpha emitting radionuclide which has demonstrated promising results in Targeted Alpha Therapy (TAT). A concern with 225 Ac is that the decay energy can break the bond to the targeting vehicle, resulting in the ...

Adaptive multi‐level differential coupling control strategy for dual‐motor servo synchronous system based on global backstepping super‐twisting control

IET Control Theory & Applications
A new dual‐motor servo steering system with improved reliability and safety is proposed. But, despite the advantages of the proposed servo system, it is strongly coupled, non‐linear and multivariable, where the biggest challenge lies in its tracking and ...

Adaptive fault‐tolerant control of a nonlinear 2‐DOF helicopter system with prescribed performance

IET Control Theory & Applications
This study investigates a novel tracking control with prescribed performance for an uncertain nonlinear 2‐DOF helicopter subject to actuator failure. The control design aims to address partial actuator faults, and to mitigate their effects, an adaptive ...
