Disturbance Observer-Based Control to Guarantee a Sliding Mode Without Sliding Mode Control
This paper presents a novel disturbance observer (DOB)-based control method to prevent the deterioration of transient response due to disturbances. The proposed method uses sliding mode dynamics without a sliding mode control (SMC) structure and does not

Induction motor IFOC based speed-controlled drive with asymptotic disturbance compensation [PDF]
This paper presents the design of digitally controlled speed electrical drive, with the asymptotic compensation of external disturbances, implemented by using the IFOC (Indirect Field Oriented Control) torque controlled induction motor.

An extensive survey of the estimation of uncertainties from missing higher orders in perturbative calculations [PDF]
We consider two approaches to estimate and characterise the theoretical uncertainties stemming from the missing higher orders in perturbative calculations in Quantum Chromodynamics: the traditional one based on renormalisation and factorisation scale ...

Beta-1 adrenergic agonist treatment mitigates negative changes in cancellous bone microarchitecture and inhibits osteocyte apoptosis during disuse. [PDF]
The sympathetic nervous system (SNS) plays an important role in mediating bone remodeling. However, the exact role that beta-1 adrenergic receptors (beta1AR) have in this process has not been elucidated.

A safety analysis approach to clinical workflows : application and evaluation [PDF]
Clinical workflows are safety critical workflows as they have the potential to cause harm or death to patients. Their safety needs to be considered as early as possible in the development process.

Performance‐enhanced iterative learning control using a model‐free disturbance observer
This paper proposes a novel performance‐enhanced iterative learning control (ILC) scheme using a model‐free disturbance observer (DOB) to achieve high performance for precision motion systems that encounter non‐repetitive disturbances.
