A method for link bandwidth management between two devices in communication through a bus in a computer system. Whether a change condition of the bus having a link is activated is monitored. Change a bandwidth of the bus from a first bandwidth with a first width and a first speed to a target bandwidth with a second width and the first speed or with the first width and a second speed when the change condition of the bus is activated. The bus will operate at the target bandwidth without disabling the link or powering down the computer system if subsequent failure speed management and unreliable speed management have passed.

An engine speed management control system for machines such as cold planers to regulate the idle engine speed as components of the machine are operated to perform functions while the engine is idling. An auto engine speed control routine may determine a combination of active functions of the components being performed and a corresponding idle engine speed to generate sufficient power and pressurized fluid flow to perform the functions. Upon detecting a change in the combination of active functions, the algorithm may change the idle engine speed as dictated by the new combination, or may wait for a specified delay period to determine whether further changes occur to the combination of active functions.

To efficiently nm a wind turbine in varying wind speeds, the wind turbine may be configured to switch between two different electrical configurations that offer different efficiencies depending on wind speed. For example, a star configuration may be preferred during low wind speeds while a delta configuration is preferred for high wind speeds. Before switching, the power output by the turbine's generator may be driven to zero. Doing so, however, removes load from the rotor blades which cause the rotor speed to increase. Instead, the rotor speed may be controlled such that the speed stays at or above the speed of the rotor immediately before the generator power is ramped down. Maintaining rotor speed at or slightly above the current speed while switching between electrical configurations may mitigate the torque change experienced by the turbine and reduce the likelihood of structural failure.
