Adaptive power management a hierarchical/distributed system

摘要

The automatic control of electrical system (ACES) for aircraft shipboard applications was first demonstrated at the Westinghouse Aerospace Electrical Division in 1970 [4]. This system was implemented on a single computer which controlled the hardware directly with discrete signals. Presently Hierarchical and Distributed computer architectures are being evaluated [3, 14], to perform the ACES task. Westinghouse is pursuing a combined Hierarchical/Distributed architecture for its Adaptive Power Management (APM) system [5]. The Hierarchical network performs system control, conflict resolution, and top level resource monitoring and adaption/reconfiguration. The Distributed network performs the system Input/Output functions, all direct control and coordination of the peripherial hardware and the adaption/reconfiguration of their resource/control tables (see Figure 10). In addition, APM complies with the Air Forces requirement to use the standard DAIS AN/AYK-15A processor [10, 11]; the standard higherorder programming language as defined in MIL-STD-1589 [12], and interface and data bus multiplex system standard MIL-STD-1553B [8, 9].
