English | 2023 | ISBN: 1032330651 | 279 Pages | PDF (True) | 31 MB
Permanent magnet synchronous motors (PMSMs) are popular in the electric vehicle industry due to their high-power density, large torque-to-inertia ratio, and high reliability. This book presents an improved field-oriented control (FOC) strategy for PMSMs that utilizes optimal proportional-integral (PI) parameters to achieve robust stability, faster dynamic response, and higher efficiency in the flux-weakening region. The book covers the combined design of a PI current regulator and varying switching frequency pulse-width modulation (PWM), along with an improved linear model predictive control (MPC) strategy. Researchers and graduate students in electrical engineering, systems and control, and electric vehicles will find this book useful.

This book describes the most commonly methods used for the study of the internal anatomy of teeth and provides a complete review of the literature concerning the current state of research employing contemporary imaging tools such as micro-CT and CBCT, which offer greater accuracy whether using qualitative or quantitative approaches. In order to facilitate the management of complex anatomic anomalies, specific clinical protocols and valuable practical tips are suggested.


The Japanese Communist Party Permanent Opposition, but Moral Compass

This book provides an historical overview of the Japanese Communist Party from its foundation to the present. It outlines the development of the party, explores its stance on key issues and discusses how the party has set a high moral tone, avoiding compromising coalitions with other parties, being intolerant of corruption within its own ranks, and frequently and consistently opposing the ruling Liberal Democratic Party. The book also considers the internal nature of the party, which continues to have a mass membership, and which in recent years has softened its former somewhat rigid approach. The book emphasizes the importance for Japan of this moral approach as the conscience of the nation, especially as the present Abe government moves Japan to the right, even though the Japanese Communist Party has never gained power and is never likely to.
