Drum water level systems show strong disturbance, big inertia, large time delay, and non-linearity characteristics. In order to improve the antidisturbance performance and robustness of the traditional active disturbance rejection controller (ADRC), an improved linear active disturbance rejection controller (ILADRC) for drum water level is designed. On the basis of the linear active disturbance rejection controller (LADRC) structure, an identical linear extended state observer (ESO) is added with the same parameters as that of the original one.

A novel method of disturbance observer-based integral backstepping control is proposed for the two-tank liquid level system with external disturbances. The problem of external disturbances can be settled in this paper. Firstly, the mathematical model of the two-tank liquid level system is established based on fluid mechanics and principle of mass conservation. Secondly, an integral backstepping control strategy is designed in order to ensure liquid level tracking performance by making the tracking errors converge to zero in finite time. Thirdly, a disturbance observer is designed for the two-t

Todays power system is integrating increasingly variable and uncertain generation resources, especially wind power. As much of wind generators in the market contribute little or none to system inertia, power system is operated much closer to its dynamic security margin. To identify the maximum wind penetration of a power system following a pre-defined disturbance, the impact of increased wind penetration on post-disturbance stability is studied. In this paper, the disturbance is simulated by a short circuit that leads to the sudden disconnection of a large amount of load demand. When wind powe

We tested the ecosystem-wide effects of this disturbance in a BACI design using two 15 km2 areas.

In group-living species, social stability is an important trait associated with the evolution of complex behaviours such as cooperation. While the drivers of stability in small groups are relatively well studied, little is known about the potential impacts of unstable states on animal societies. Temporary changes in group composition, such as a social group splitting and recombining (i.e. a disturbance event), can result in individuals having to re-establish their social relationships, thus taking time away from other tasks such as foraging or vigilance.

Abstract The present study examines the potential of using a semi-active controllable damper, whose damping coefficient can be modulated in real-time, for narrow-band disturbance rejection applications. A frequency-domain optimal control algorithm is developed for determining the controllable damper input (of twice the disturbance frequency) that minimizes the force transmitted to the support at the disturbance frequency. The effectiveness of both open-loop and closed-loop controllers in rejecting the transmitted disturbances are evaluated. The results of the study indicate that for physically

Landscape disturbances such as forest harvest, blowdowns, fire, and development activities create patches on the landscape that modify the structure and function of ecosystems and watersheds. Understanding the timing, location, size, and intensity of these disturbances can assist resource managers in making decisions regarding management options. To provide information regarding these metrics, the Great Lakes Inventory and Monitoring Network implemented a long-term monitoring project to quantify landscape dynamics inside and surrounding Sleeping Bear Dunes National Lakeshore using an automated

For its size, Devils Postpile National Monument supports a diverse assemblage of nocturnal fauna. Our summer 2022 surveys recorded 15 bat species within the monument. Five of these species had not been previously confirmed in the monument, including two of the three sensitive species targeted: pallid bat (Antrozous pallidus) and fringed myotis (Myotis thysanodes). No California Spotted Owls (Strix occidentalis occidentalis) were confirmed, but a Great Horned Owl (Bubo virginianus) was recorded.

Climate and hydrology are major drivers of ecosystems. They dramatically shape ecosystem structure and function, particularly in arid and semi-arid ecosystems. Understanding changes in climate, groundwater, and water quality and quantity is central to assessing the condition of park biota and key cultural resources. The Sonoran Desert Network collects data on climate, groundwater, and surface water at 11 National Park Service units in south-ern Arizona and New Mexico.

Vulnerability assessments are a common approach to identifying conservation priorities for species and informing resource management decisions by evaluating species? exposure (spatial extent and frequency/intensity) and sensitivity (whether and how a species will respond) to a threat. We assessed the vulnerability of the Northern Spotted Owl (NSO; Strix occidentalis caurina) in Marin County to eight distinct threats: 1) competition with Barred Owls (S. varia); 2) climate change; 3) wildfire; 4) sudden oak death (SOD); 5) other habitat loss/disturbance, specifically from urban development or fu

Wetlands at Florissant Fossil Beds National Monument (FLFO) are important because they are biodiversity hotspots and support iconic wildlife. They also provide valuable ?ecosystem services? such as attenuating floods, storing water, recharging aquifers, stabilizing and sequestering sediment, storing carbon, enhancing water quality, and cycling nutrients. This report summarizes 11 years (2009?2019) of wetland monitoring in three sentinel wetland complexes in FLFO. Monitoring included annual samples of 10 wet meadow and fen wetland sites in these complexes. We partition the data into a baseline

The uncertainty around the impacts of changing climate poses a significant challenge to sustaining forest ecosystems in the Northeast. Important work has been done downscaling projected changes in climate conditions, modeling shifts in suitable habitat, and mapping disturbance patterns across the region, but no one effort has combined all these predictive tools into one cohesive dataset. The goal of this project is to aggregate these valuable but disparate spatial data sets to quantify a more comprehensive assessment of relative exposure to climate change impacts at the species, and community

Rationale. Earth scent is the odour emitted from soils. This scent, primarily comprising the alcohols geosmin and 2-methylisoborneol (MIB), has not been fully characterised, but offers high potential for use as an environmental interrogation tool. Methodology. We utilised our field- based, solid-phase microextraction fibre method to test the hypothesis that soil activity and soil property variation can be detected in situ by comparing biogenic volatile emissions. Results. We eliminated sources of error utilising field-based sampling with these fibres, concluding that room temperature storage f

Highly acute mental illness and acute severe behavioural disturbance (ASBD) are two of the most challenging problems faced by Mental Health Intensive Care Units (MHICU). ASBD is defined as behaviour that places the patient or others at imminent risk of injury or death. It includes extreme distress, aggression, and serious self-harm, in the context of mental illness. This Evidence Check assessed the literature on models of care and treatment strategies for these conditions, aiming to refine the model used in MHICU in NSW.

For school age children on the island of Puerto Rico, the back-to-back hurricane strikes of Irma and Maria were their first experience with the tragedy of hurricanes in Puerto Rico. There is much concern in the general public about the ability of the Puerto Rican forests, like El Yunque, to recover. These concerns reveal common misconceptions about the dynamics of forest ecosystems. The focus of this research is Journey to El Yunque, a middle school curriculum unit that engages students in evidence-based modeling of hurricane disturbance using long-term data about population dynamics after Hur
