Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.

After a brief introduction to the main law of physics and fundamental concepts inherent in electromechanical conversion, Vector Control of Induction Machines introduces the standard mathematical models for induction machines – whichever rotor technology is used – as well as several squirrel-cage induction machine vector-control strategies. The use of causal ordering graphs allows systematization of the design stage, as well as standardization of the structure of control devices. Vector Control of Induction Machines suggests a unique approach aimed at reducing parameter sensitivity for vector controls based on a theoretical analysis of this sensitivity. This analysis naturally leads to the introduction of control strategies that are based on the combination of different controls with different robustness properties, through the use of fuzzy logic supervisors. Numerous applications and experiments confirm the validity of this simple solution, which is both reproducible and applicable to other complex systems. Vector Control of Induction Machines is written for researchers and postgraduate students in electrical engineering and motor drive design.

A voltage converter changes the voltage of an electrical power source and is usually combined with other components to create a power supply. This title is devoted to the control of static converters, which deals with pulse-width modulation (PWM) techniques, and also discusses methods for current control. Various application cases are treated. The book is ideal for professionals in power engineering, power electronics, and electric drives industries, as well as practicing engineers, university professors, postdoctoral fellows, and graduate students.

Despite increasingly open markets and a pervasive move toward international production methods, national governments continue to pursue remarkably distinctive policies for promoting innovation in industry. J. Nicholas Ziegler analyzes this apparent paradox by comparing government efforts to promote technological advance in Germany and France. His findings reveal a great deal about the roots and limits of public strategies for economic growth. Through close comparison of three technologies— digital telephone exchanges, computer-controlled machine tools, and semiconductors—Ziegler shows how each country displays predictable strengths and weaknesses in promoting innovation. These distinctive capacities depend more upon the links among different skill- and knowledge-bearing elites than on the structure of the state or the industrial sector in question. As business outcomes hinge less on economies of scale and more on knowledge-based competition, the politics of contending interest groups steadily gives way to a competition for status and jurisdiction among more specialized professional groups. As a result, Germany's strengths stem directly from what Ziegler calls an ethos of competence whereas France's strengths stem from an order of state-created elites. More generally, Ziegler contends, neo-institutional approaches to public policy need to pay far more attention to the professional identities of different occupational groups.
