Permanent magnet synchronous motors (PMSMs) have been widely used in the electric vehicles (EVs) due to their high-power density, large torque-to-inertia ratio, high reliability, etc. This book involves emerging control strategies of the non-salient and salient PMSMs operating in the flux-weakening region. The optimization algorithms, such as adaptive velocity particle swarm optimization (AVPSO) and genetic optimization (GA) algorithms, are also presented, including the offline optimization procedures. The advanced control strategies like improved field-oriented control (FOC) and model-predictive control (MPC) are explicitly investigated in detail. The parameters optimization presented in this book is based on the new cost function of the error value matrix for the proportional-integral (PI) controllers. A new cost function is deduced from the Taylor series expansion form to obtain the linearized equilibrium part of the advanced control strategy. Additionally, the stability terms are considered to obtain high performance in speed tracking at the flux-weakening region. In this book, a real-time AVPSO algorithm is used in the continuous control model predictive control.

Public corporations and private businesses operate in an increasingly complex, uncertain, and interconnected world. When evaluating investment decisions, business managers can no longer base their decisions primarily on expected financial return. They now must now consider a host of performance value measures (i.e., criteria) pertaining to issues such as environmental and social governance, sustainability, and stakeholder satisfaction. In addition, corporate managers must ensure that their investment decisions are aligned with the company's vision, mission, and values in order to maintain investor confidence and protect brand image. Lastly, to be truly successful, business managers must assess the risks associated with each performance measure and manage their impacts during project implementation. This book takes a pragmatic business and economics view towards evaluating competing investment alternatives and/or capital project strategies. It provides a practical step-by-step process using a structured decision analysis framework to evaluate, understand, quantify, and measure project invesment strategies in light of multiple stakeholder objectives and success criteria.
