Enhancing Reference Tracking in Induction Motor Drives: A Hybrid Model Predictive Control and Artificial Neural Network Approach

International Journal of Robust and Nonlinear Control, Volume 36, Issue 14, Page 6719-6738, 25 September 2026.
ABSTRACT Induction motors (IMs) are widely used in industry for their robustness and cost‐effectiveness, yet their nonlinear and multivariable dynamics pose significant challenges for high‐performance speed control. Model Predictive Control (MPC) is a well‐established solution but suffers from limitations related to model accuracy and parameter ...

Formation control of vessels with intermittent communication

Zhongguo Jianchuan Yanjiu, 2020
Objectives Aiming at the formation control of multiple vessels in an intermittent communication environment, a coordinated formation control law based on the backstepping method is proposed, and sufficient conditions for formation given to ensure ...

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Glacial Imprints and Marine Overprints: Sediment Architecture and Fjord Evolution in Fiordland, New Zealand

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Fjords are globally significant sedimentary archives that record the relationship between glacial, tectonic, and marine processes. Fiordland, on the southwest coast of New Zealand, hosts one of the most extensive temperate fjord provinces in the Southern Hemisphere, yet its postglacial evolution has remained poorly constrained.

Adaptive Control of a Piezo-Positioning Mechanism With Hysteresis and Input Saturation Using Time Delay Estimation

IEEE Access, 2020
In this paper, based on backstepping technique and time delay estimation (TDE) technique, an adaptive time delay compensation control scheme is developed for a class of piezoelectric positioning mechanical systems with Bouc-Wen hysteresis and input ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Sequential Wedge Extrusion to Core Complex Extension: The Central Cycladic Detachment System on Syros, Greece

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Syros island preserves pristine high‐pressure metamorphic rocks and provides invaluable insight into subduction zone processes. Contrasting views on the structural history impede placing the island in a clear tectonic framework, limiting the broader impact of preserved information.

Adaptive backstepping with a high-order tuner

Automatica, 2001
Adaptive backstepping and high-order tuners were proposed and investigated actively by several researchers in the 1990s, and they are undoubtedly important results in the history of adaptive control. This work combines those two methodologies to construct adaptive nonlinear control systems.

NONLINEAR ADAPTIVE HEADING CONTROL FOR AN UNDERACTUATED SURFACE VESSEL WITH CONSTRAINED INPUT AND SIDESLIP ANGLE COMPENSATION

Brodogradnja, 2020
In this paper, a nonlinear adaptive heading controller is developed for an underactuated surface vessel with constrained input and sideslip angle compensation. The controller design is accomplished in a framework of backstepping technique.

COMPARISON OF AN X4-AUV PERFORMANCE USING A BACKSTEPPING AND INTEGRAL BACKSTEPPING APPROACH

Jurnal Teknologi, 2016
X4-AUV is a type of an autonomous underwater vehicle (AUV) which has 4 inputs with six degrees of freedoms (6-DOFs) in motion and is classified under an underactuated system. Controlling an underactuated system is difficult tasks because of the highly nonlinear dynamic, uncertainties in hydrodynamics behaviour and mostly those systems fails to satisfy ...
