This paper presents an original variable gain PI (VGPI) controller for speed control of a direct torque neuro fuzzy controlled (DTNFC) induction motor drive. First, a VGPI speed controller is designed to replace the classical PI controller in a conventional direct torque controlled induction motor drive. Its simulated performances are then compared to those of a classical PI controller. Then, a...
Background We assessed direct and indirect costs associated with COPD in Sweden and examined how these costs vary across time, age, and disease stage in a cohort of patients with COPD and matched controls in a real-world, primary care (PC) setting. Patients and methods Data from electronic medical records linked to the mandatory national health registers were collected for COPD patients and a...
HCV can cause psychiatric disorders. It is crucial to re-evaluate them with direct-acting antiviral treatment (DDAs), since the interferon-based treatments of past were capable causing identical adverse effects. A system multidisciplinary team (MDT) meetings was implemented in France December 2014 regional reference centers aim controlling prescription and administration these new treatments, a...
This paper proposes a back electromotive force estimation error compensation method for accurate rotor position estimation of surface mounted permanent magnet synchronous motors. When estimating the rotor position of surface mounted permanent magnet synchronous motor sensorless drives, a direct current offset error component occurs in the voltage sensor. As a result, the rotor position is disto...
