Experimental Verification of Lead-Lag Compensators on a Twin Rotor System

open access: yesElectrical, Control and Communication Engineering, 2018
Twin rotor system is a laboratory setup resembling a simplified helicopter model that moves along both horizontal and vertical axes. The literature on control of twin rotor systems reflects a good amount of research on designing PID controllers and their

Point-to-point control of a 2R planar horizontal underactuated manipulator [PDF]

open access: yes, 2006
This paper presents a control strategy for a two-link manipulator with revolute joints (2R) with an unactuated second joint, wherein the motion of the system is confined to a horizontal plane. The model takes into account the frictional forces present in

A Nonlinear Controller for Point-to-Point Position Control

open access: yesEnergies, 2023
Position control algorithms can be classified into two groups: point-to-point control and continuous path control. For point-to-point control implemented in programmable logic controllers, the speed setpoint is mostly the only setpoint transmitted to the

Positive, negative and controlled durotaxis

open access: yesSoft Matter, 2023
Durotaxis is a physical process central to life, including embryogenesis, tissue regeneration, and tumor growth. This work proposes a mechanistic rationale for durotaxis based on the clutch hypothesis and active gels.

Review of the Flight Control Method of a Bird-like Flapping-Wing Air Vehicle

open access: yesMicromachines, 2023
The Bird-like Flapping-wing Air Vehicle (BFAV) is a robotic innovation that emulates the flight patterns of birds. In comparison to fixed-wing and rotary-wing air vehicles, the BFAV offers superior attributes such as stealth, enhanced maneuverability ...

Distribution characteristics of soil crusts under two kinds of aerial seeding plants in the northeastern margin of Tengger Desert

open access: yesFrontiers in Environmental Science
In order to explore the effects of two plants on the spatial distribution and nutrient distribution of crusts in different directions and distances after 30 years of aerial seeding, as well as the relationship between crust thickness and nutrient content,

Enhanced fine soil aggregation and organic matter accumulation facilitated by Salix Psammophila sand barriers along desert highways

open access: yesFrontiers in Environmental Science
Desert ecosystems are inherently nutrient-limited and highly susceptible to disturbances. In such arid environments, sand barriers play a pivotal role in ecological restoration efforts. Despite their importance, the long-term effects of Salix Psammophila

Geochemical indicators to constrain weathering, provenance and tectonic setting of the Pisha Sandstone (Early–Middle Triassic) in Northeast Ordos Basin, China

open access: yesHeliyon
The Pisha Sandstone is widely exposed in the northeastern margin of the Ordos basin. Since the Mesozoic the basin was subjected to uneven uplift several times, strong weathering and erosion have been occurring and a large amount of sediments derived from
