摘要:
A controller capable of being employed in a distributed control system, where the distributed control system controls operations of a plurality of devices that operate together to perform a process, and a method of communicating information between a first program portion and a second program portion of such a controller, are disclosed. The controller includes at least one processing component configured to perform a first plurality of program portions that operate in relation with one another as a first agent. The plurality of program portions includes a first program portion that controls agent-type behavior of the controller, and a second program portion that at least one of controls and monitors at least one of the devices. The controller further includes at least one memory component that stores a data table that is accessed by each of the first and second program portions to allow communication between those program portions.

摘要:
A Multiple-Agent Hybrid Control Architecture (MAHCA) uses agents to analyze design, and implement intelligent control of distributed processes. A single agent can be configured to control a local process and a network of agents can be configured to control more complex distributed processes. Multiple agents interact through messages and can be either permanent or temporary. The network of agents interact to create an emergent global behavior. The network of agents support construction of closed-loop, autonomous systems which react to comply with two degrees of freedom: (1) a logic degree of freedom (useful for implementing switching between modes of control) and (2) an evolution degree of freedom (useful for implementing particular modes of control). Global behavior is emergent from individual agent behaviors and is achieved without central control through the imposition of global constraints on the network of individual agent behaviors (the logic agent network). MAHCA is especially useful for reactive synchronization of real-time distributed processes subject to decision-making under uncertainty where both logical and evolution constraints on system operation must be continuously maintained and where human operators must be kept appraised of current system operation and whose decisions must be promptly and safely executed. MAHCA also provides support for reuse of existing trusted components and incremental provision of expanded functionality in old or new components through formal construction of provably correct real-time software from declarations of desired logic and evolution behavior of system components. Finally, MAHCA agents can be used in conventional digital procedures to speed up an ensemble of procedures.

A controller configured to operate as at least one agent, a method of configuring a controller for operation as part of a multi-agent distributed control system, and a configuration device for so configuring a controller, are disclosed. The controller includes at least one processing device and at least one storage medium that is in communication with the at least one processing device. The at least one storage medium stores a plurality of program portions that are executed by the at least one processing device, and the plurality of program portions includes first, second and third program portions. The first program portion is capable of generating first signals that are commands to be provided to a controlled device, the second program portion is capable of governing standard agent-type functionality, and the third program portion is capable of governing application-specific agent-type functionality.

摘要:
A Multiple-Agent Hybrid Control Architecture (MAHCA) uses agents to analyze design, and implement intelligent control of distributed processes. A network of agents can be configured to control more complex distributed processes. The network of agents interact to create an emergent global behavior. Global behavior is emergent from individual agent behaviors and is achieved without central control through the imposition of global constraints on the network of individual agent behaviors. Agent synchronization can be achieved by satisfaction of an interagent invariance principle. At each update time, the active plan of each of the agents in the network encodes equivalent behavior modulo a congruence relation determined by the knowledge clauses in each agents's knowledge base. The Control Loop and the Reactive Learning Loop of each agent can be implemented separately. This separation results in an implementation runs faster and with less memory requirements than an unseparated arrangement. A Direct Memory Map (DMM) is to implement the agent architecture. The DMM is a procedure for transforming knowledge and acts as a compiler of agent knowledge by providing a data structure called memory patches, which are used to organize the knowledge contained in each agent's Knowledge Base. Content addressable memory is used as the basic mechanism of the memory patch structure. Content addressable memory uses a specialized register called the comparand to store a pattern that is compared with contents of the memory cells. The DMM has two comparands, the Present State Comparand and the Goal Comparand. The MAHCA can be used for compression/decompression for processing and storage of audio or video data.
