The Booting‐Type ADRC of Airborne Photoelectrical Platform [PDF]
Mathematical Problems in Engineering, 2014 Customary disturbance rejection in the photoelectrical platform is “passive,” which makes it difficult to further improve the isolation degree owning to the strict restriction of mechanical resonance frequency. In this paper, a booting‐type ADRC is proposed, whose disturbance estimation process is guided by target value to reduce the overshoot and lag ...

An improved ADRC and its Application
Advances in Intelligent Systems Research, 2014 Electro-hydraulic servo control system has a typical large delay, nonlinear and time-varying characteristics, which is Controlled effectively by using ADRC. To optimize the parameters of ADRC quickly, the paper presents a new ADRC structure of configurable zero point, and analysis the effect of strong interference on the extended state observer, and ...

Annals of Neurology, EarlyView.Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...
