TL;DR: By targeting the use of fault-tolerance, this paper is able to obtain significant reductions in computer energy expenditure and thermal stress without lowering the reliability and has beneficial effects on processor lifetime and required energy storage.
Abstract: The energy consumption of the cyber part of cyber-physical systems (CPSs) has attracted considerable attention in recent years. Increased energy consumption results in increased thermal damage to the processors requiring more frequent replacements; and in many applications, it also requires increased energy storage capacity. Fault tolerance contributes to a large fraction of the cyber energy consumption in CPS since it is implemented using redundant computations.This paper studies the use of dynamic actuator derating (i.e., artificially limiting the maximum actuator output) for reducing the required redundancy. By targeting the use of fault-tolerance, we are able to obtain significant reductions in computer energy expenditure and thermal stress without lowering the reliability. This has beneficial effects on processor lifetime and required energy storage.

TL;DR: In this article, a braking system is described, which includes a controller configured to determine a power limit for one or more brakes of a machine based on a temperature of the one or multiple brakes during engagement of the brakes according to a commanded power.
Abstract: A braking system is disclosed. The braking system may include a controller configured to determine a power limit for one or more brakes of a machine based on a temperature of the one or more brakes during engagement of the one or more brakes according to a commanded power. The power limit may be a power at which the temperature of the one or more brakes ceases to increase. The controller may be configured to determine a speed adjustment for the machine based on the power limit and the commanded power, and cause adjustment to a speed of the machine based on the determined speed adjustment.

TL;DR: In this article, a method for controlling the distribution of power to a traction motor in a plug-in electric vehicle having a plurality of on-board sources of electric power is presented.
Abstract: A method for controlling the distribution of power to a traction motor in a plug-in electric vehicle having a plurality of on-board sources of electric power. Power is distributed at a normal power control relationship in response to an operator control input during operation in a normal mode. Power is depleted at a first rate during operation of the vehicle in the normal mode. Power is distributed at a derate power control relationship in response to the operator control input during operation in a derate mode. Power is depleted at a second rate that is less than the first rate during operation in the derate mode to conserve the power of the one or more on-board sources. Operation in the derate mode can be initiated in response to information from sensors identifying a vehicle condition indicating a battery charge limitation.
