A New Approach to Nonlinear State Observation for Affine Control Dynamical Systems
Applied Sciences, 2023 In this work, a Nonlinear Higher Order Extended State Observer (NHOESO) is presented to replace the Linear Extended State Observer (LESO) used in Conventional Active Disturbance Rejection Control (C-ADRC) solutions.

Nested Models and Model Uncertainty [PDF]
The Scandinavian Journal of Economics, 2015 AbstractUncertainty about the appropriate choice among nested models is a concern for optimal policy when policy prescriptions from those models differ. The standard procedure is to specify a prior over the parameter space, ignoring the special status of submodels (e.g., those resulting from zero restrictions).

Dasymetric Modeling and Uncertainty [PDF]
Annals of the Association of American Geographers, 2013 Dasymetric models increase the spatial resolution of population data by incorporating related ancillary data layers. The role of uncertainty in dasymetric modeling has not been fully addressed as of yet. Uncertainty is usually present because most population data are themselves uncertain, and/or the geographic processes that connect population and the ...

Journal of Advances in Modeling Earth Systems, 2023 The selection of physical parameterization schemes for tropical cyclone (TC) forecasts has required a substantial amount of effort. In general, the evaluation of physical parameterization schemes and their combined performance was based solely on the ...

Biomass Estimation and Uncertainty Quantification From Tree Height
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 We propose a tree-level biomass estimation model approximating allometric equations by LiDAR data. Since tree crown diameter estimation is challenging from spaceborne LiDAR measurements, we develop a model to correlate tree height with biomass on the ...

UNCERTAINTY IN TMDL MODELS [PDF]
Transactions of the ASABE, 2006 Although the U.S. Congress established the Total Maximum Daily Load (TMDL) program in the original Clean Water Act of 1972, Section 303(d), it did not receive attention until the 1990s. Currently, two methods are available for tracking pollution in the environment and assessing the effectiveness of the TMDL process on improving the quality of impaired ...

Robust Sliding Mode Control With Optimal Path Following for Lateral Motion of Autonomous Bus
IEEE Access, 2023 A robust and high-performance lateral control system is necessary for autonomous bus driving in complex downtown roads. In this paper, a Sliding Mode (SM) controller with an uncertainty observer is proposed to reduce the chattering phenomenon while ...
