Low-Cost Current-Fed PMSM Drive System With Sinusoidal Input
... The three-phase step-down rectifier operation is based on the fact that the dc link inductor current is switched between the input phases such that the equivalent area per switching cycle reconstitutes a sine-wave current on that phase in the lower part of its harmonic spectrum. Therefore, to sinuso ...

Resilient control systems
![](https://en.wikipedia.org/wiki/Special:FilePath/RCS_Architecture_09-50368.jpg?width=300)
In our modern society, computerized or digital control systems have been used to reliably automate many of the industrial operations that we take for granted, from the power plant to the automobiles we drive. However, the complexity of these systems and how the designers integrate them, the roles and responsibilities of the humans that interact with the systems, and the cyber security of these highly networked systems has led to a new paradigm in research philosophy for next generation control systems. Resilient Control Systems consider all of these elements and those disciplines that contribute to a more effective design, such as cognitive psychology, computer science, and control engineering to develop interdisciplinary solutions. These solutions consider such things such as how to tailor the control system operating displays to best enable the user to make an accurate and reproducible response, how to design in cyber security protections such that the system defends itself from attack by changing its behaviors, and how to better integrate widely distributed computer control systems to prevent cascading failures that result in disruptions to critical industrial operations. In the context of cyber-physical systems, resilient control systems are an aspect that focuses on the unique interdependencies of a control system, as compared to information technology computer systems and networks, due to its importance in operating our critical industrial operations.
