1. AC power networks, controlled by either the distributed averaging integral (or DAI) controller or the leaky integral (or LI) controller, enjoy stability as well as robustness to a class of measurement and actuation errors.
Chapters 3 and 4 2. Both the DAI controller and the LI controller can be tuned using their respective parameters to balance controller performance and robustness, without sacrificing fair power sharing. Chapters 3 and 4 3. The DAI controller requires a connected communication network. How-ever, it is able to cope with communication problems, operating correctly even if the network is only intermittently available. Chapter 2 4. Though the LI controller requires no communication, it also does not offer exact frequency regulation. This makes the DAI controller the superior choice if a communication network is available. Chapters 3 and 4 5. DC power networks in which nodes are connected by resistive transmission lines can be stabilized by decentralized consensus-based controllers, and additionally can be made to enjoy proportional power sharing among the
power sources. Chapter 5
6. DC power networks in which nodes are connected by resistive-inductive transmission lines can also be stabilized by decentralized consensus-based controllers, and additionally can be made to enjoy power sharing among
the power sources. Chapter 6
7. The word ‘security’ is used differently in cryptography than it is in control, but in both fields it is not a question answered by ‘yes’, but a character-ization of the extent of the system’s resistance to an attack.
