Control Algorithms Clause Samples
Control Algorithms. MAC protocol algorithms attempt to ensure that no member of the extended beacon group transmits a beacon frame at the same time as the device. Information included in beacon frames facilitates contention-free frame exchanges by ensuring that a device does not transmit frames while a neighbor is transmitting or receiving frames. To permit correct frame reception, MAC protocol algorithms attempt to ensure that a device’s DevAddr is unique within the device’s extended beacon group.
Control Algorithms. There are two control algorithms (controllers) executed depending on the satellite operational mode. They are used for coarse and fine pointing control. The control algorithms are executed only when a certain operational mode is reached, meaning that in Off and Standby modes, no controller is executing. Consequently, while the CDMU (Central Data Management Unit) is rebooting, no controller is executing. When during the transition to Safe mode all necessary unit configurations for this mode are completed, then the Mode Manager selects an adequate controller for this mode – coarse pointing controller and initiates its preparation for execution. After preparation phase reaches some predefined time limit, in case there are no ongoing unit reconfigurations, the controller is accepted as ready for execution. Similarly, when during the transition to Nominal mode all necessary unit configurations for this mode are completed, the Mode Manager selects fine pointing controller and initiates its preparation for execution, which starts after preparation phase reaches some predefined time limit, unless there is an ongoing unit reconfiguration.
