Transactions of Nonferrous Metals Society of China, 2022 : This study aimed to elucidate the strength weakening effect of high static pre-stressed rocks subjected to low-frequency disturbances under uniaxial compression. Based on the uniaxial compressive strength (UCS) of granite under static loading, 70%, 80%,

Dynamic Disturbance Decoupling for Nonlinear Systems [PDF]
SIAM Journal on Control and Optimization, 1992 Summary: In analogy with the dynamic input-output decoupling problem the dynamic disturbance decoupling problem for nonlinear systems is introduced. A local solution of this problem is obtained in the case that the system under consideration is invertible. The solution is given in algebraic as well as in geometric terms.

Non-dynamism and temporal disturbances [PDF]
Synthese, 2023 AbstractPhilosophical accounts denying that temporal passage is an objective feature of reality face an explanatory challenge with respect to why it appears to us as though time passes. Recently, two solutions have surfaced. Cognitive illusionism claims that people experience the passage of time due to their belief that time passes.

SAW torque transducers for disturbance rejection and tracking control of multi-inertia servo-drive systems [PDF]
, 2004 The paper proposes a resonance ratio control (RRC) technique for the coordinated motion control of multi-inertia mechanical systems, based on the measurement of shaft torque via a SAW-based torque sensor. Furthermore, a new controller structure, RRC plus

Synchronization of Fractional-Order Chaotic Systems with Model Uncertainty and External Disturbance
Mathematics, 2021 This paper is concerned with complete synchronization of fractional-order chaotic systems with both model uncertainty and external disturbance. Firstly, we propose a new dynamic feedback control method for complete synchronization of fractional-order ...

Observer-based tuning of two-inertia servo-drive systems with integrated SAW torque transducers [PDF]
, 2007 This paper proposes controller design and tuning methodologies that facilitate the rejection of periodic load-side disturbances applied to a torsional mechanical system while simultaneously compensating for the observer’s inherent phase delay.
