Enhancing Performance and Reliability of Hf1‐xZrxO2 Morphotropic Phase Boundary Films via Nanolaminate Structuring and Microwave Annealing

Advanced Materials Technologies, EarlyView.
Hf–Zr–O‐based morphotropic phase boundary (MPB) thin films often suffer from limited endurance and poor uniformity due to intrinsic phase instability. This work proposes a nanolaminate architecture that spatially separates competing phases, stabilizes phase formation, and suppresses wake‐up‐induced degradation.

PREDICTIVE CONTROL FOR AC-DRIVES

IFAC Proceedings Volumes, 1989
Abstract AC-drives are controlled by field or decoupling control. These solutions enable the control of the flux and the torque independently. For good dynamic response a good dynamic behaviour of these current control loops is necessary. Good dynamic response needs a high sampling rate and a high switching frequency of the inverter.

Introduction to AC Drives

1996
Abstract An important factor in worldwide industrial progress during the past several decades has been the increasing sophistication of factory automation. Manufacturing lines in an industrial plant typically involve one or more variable speed motor drives which serve to power conveyor belts, robot arms, overhead cranes, steel process

AC drives in the metals industry

Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003
The use of alternating current (AC) drives in the metals industry has greatly increased in the last 15 years. This increase appears to be the result of increasing features of drives, more reliable motors and electronics, smaller cost efficient packages, and end user education on applying AC drives.

DSP application in AC drives

2000 10th Mediterranean Electrotechnical Conference. Information Technology and Electrotechnology for the Mediterranean Countries. Proceedings. MeleCon 2000 (Cat. No.00CH37099), 2005
The analog control systems were a unique way for implementation in AC drives control for many years. The implementation of microprocessors in the AC drives control has begun in the speed and position loops. The slow speed (position) change allows implementation of 8 or 16 bit microprocessors.

Application Considerations for AC Drives

IEEE Transactions on Industry Applications, 1983
General application considerations for ac variable-frequency drives are discussed. A review of induction motor characteristics and adjustable frequency controller fundamentals is presented as a background for applying the drives. In addition, a brief review of the types of controllers available is provided.
