Extended State Observer-Based Predictive Speed Control for Permanent Magnet Linear Synchronous Motor [PDF]

Processes, 2019
Combining the feedback of predictive function control and the feedforward of extended state observer, a composite control strategy is proposed for the permanent magnet linear synchronous motor (PMLSM). The mathematical model of the PMLSM vector control system is established based on the basic structure and operation mechanism of PMLSM.

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

An Improved Two-Degree-of-Freedom Speed Controller for Permanent-Magnet Synchronous Motors

Energies
For the traditional one-degree-of-freedom controller, there is a trade-off between the tracking performance and disturbance rejection performance.

High-gain nonlinear observer for simple genetic regulation process

, 2007
High-gain nonlinear observers occur in the nonlinear automatic control theory and are in standard usage in chemical engineering processes. We apply such a type of analysis in the context of a very simple one-gene regulation circuit.

Parent‐to‐Child Information Disclosure in Pediatric Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

A reduced-order extended state observer–based trajectory tracking control for one-degree-of-freedom pneumatic manipulator

Advances in Mechanical Engineering, 2018
In this article, a reduced-order extended state observer is proposed to deal with uncertainties and disturbances in tracking control for a one-degree-of-freedom manipulator pneumatic system.

Comparison of linear and nonlinear active disturbance rejection control method for hypersonic vehicle [PDF]

, 2016
Near space hypersonic vehicles have features of strong coupling, nonlinearity and acute changes in aerodynamic parameters, which are challenging for the controller design. Active disturbance rejection control (ADRC) method does not depend on the accurate
