A NARX Model Reference Adaptive Control Scheme: Improved Disturbance Rejection Fractional-Order PID Control of an Experimental Magnetic Levitation System

Algorithms, 2020
Real control systems require robust control performance to deal with unpredictable and altering operating conditions of real-world systems. Improvement of disturbance rejection control performance should be considered as one of the essential control ...

A new species of Hortipes (Araneae, Corinnidae), the first spider with an insertable retrolateral tibial apophysis on the male palp [PDF]

, 2012
Hortipes gigapophysalis (Araneae, Corinnidae) is a new species described from both sexes from montane forest on Mt Nimba, eastern Guinea. The species is remarkable for its long, whip-shaped retrolateral tibial apophysis (RTA) on the male palp.

Enhanced Control Strategies for Lower Limb Rehabilitation Robots: A Comparative Study of MRAC, PID‐ZN, and MRAC‐PSO Controllers

Applied Bionics and Biomechanics, Volume 2026, Issue 1, 2026.
Wearable robots for rehabilitation have dramatically advanced the medical field regarding helping patients suffering from lower limb impairments to regain mobility and ameliorate their range of motion (ROM). However, to further optimize control mechanisms within these robots, conventional methods cannot adapt to the different needs of patients in their

Research on Independent Reference Model–Based Anti‐Interference Control for Quadrotor

Journal of Control Science and Engineering, Volume 2026, Issue 1, 2026.
The quadrotor is vulnerable to internal model parameters uncertainty and external airflow. In order to guarantee that the quadrotor tracks the reference signal quickly and smoothly under the influence of external airflow interferences and internal parameter uncertainties, an independent reference model–based anti‐interference control algorithm was ...

Design of Lyapunov rule based model reference adaptive control with decoupler for petroleum distillation column control

Discover Applied Sciences
The petroleum industry heavily relies on distillation as a key separation technique for product purification. However, controlling the petroleum distillation columns is challenging due to their highly nonlinear nature, interactions between variables, and

Functional Morphology of the Scaphoid in Extant African Apes, Humans and Fossil Hominins

American Journal of Biological Anthropology, Volume 188, Issue 4, December 2025.
ABSTRACT Objectives The morphology of the hominoid scaphoid has played a key role in functional and evolutionary hypotheses related to the emergence of hominin bipedalism and tool use. However, the scaphoid's complex morphology is challenging to comparatively analyze via traditional 2D linear measurements.

Precise orientation control of gimbals with parametric variations using model reference adaptive controller

IET Control Theory & Applications
This study focuses on a model reference adaptive control method that ensures identical orientation outputs for different prototypes of a two‐axis gimbal produced in mass production. In this method, unlike traditional MRAC structures, an MRAC structure is

Normalized Model Reference Adaptive Control Applied to High Starting Torque Scalar Control Scheme for Induction Motors

Energies, 2022
Recently, a novel high-starting torque scalar control scheme (HST-SCS) for induction motor(s) (IM) emerged. It expands the scalar control application field beyond centrifugal pumps, blowers, and fans, moving, for instance, some conveyor belts with ...

Model-reference adaptive control based on neurofuzzy networks [PDF]

, 2004
Model reference adaptive control (MRAC) is a popular approach to control linear systems, as it is relatively simple to implement. However, the performance of the linear MRAC deteriorates rapidly when the system becomes nonlinear.
