Onrobustness of anAMBsuspended energy storage flywheel platform under characteristicmodel based all-coefficient adaptive control laws None

Xujun LYU, Long DI, Zongli LIN

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 1,   Pages 120-130 doi: 10.1631/FITEE.1800606

Abstract:

A characteristic model based all-coefficient adaptive control law was recently implemented on an experimental test rig for high-speed energy storage flywheels suspended on magnetic bearings. Such a control law is an intelligent control law, as its design does not rely on a pre-established mathematical model of a plant but identifies its characteristic model while the plant is being controlled. Extensive numerical simulations and experimental results indicated that this intelligent control law outperforms a μ-synthesis control law, originally designed when the experimental platform was built in terms of their ability to suppress vibration on the high-speed test rig. We further establish, through an extensive simulation, that this intelligent control law possesses considerable robustness with respect to plant uncertainties, external disturbances, and time delay.

Polycystic ovary syndrome

Frontiers of Medicine 2010, Volume 4, Issue 3,   Pages 280-284 doi: 10.1007/s11684-010-0098-2

Abstract: Polycystic ovary syndrome (PCOS) is a common gynecologic endocrinopathy. The pathogenesis of PCOS is associated with both heredity and environment. PCOS has adverse impacts on female endocrine, reproduction, and metabolism. PCOS can impact women’s reproductive health, leading to anovulatory infertility and higher rate of early pregnancy loss. PCOS has additional metabolic derangements, such as insulin resistance, impaired glucose tolerance, and dyslipidemia. The risks of diabetes, cardiovascular disease, hypertension, metabolic syndrome, and endometrial cancer among PCOS patients are significantly increased as well.
