摘要： A new process is synchronized to an existing process in the face of a communications delay (d) by collecting a history of delayed measurements and states of the existing process. This history and predetermined information regarding the behavior of the existing process are used to simulate the existing process forward in time to a current time, thereby computing a current process state. Once the current state is computed, the new process, driven by the same information, maintains synchronization with the existing process. In a document processor the method of synchronizing can be applied to tightly coupled modules. For example, a print media transport system includes a plurality of transport modules. Each transport module includes a plurality of transport actuators and an associated controller. Print media may be driven by actuators of plural modules contemporaneously. Modules about to receive media are synchronized to modules already transporting the media.

摘要： Respective coordinators are spawned or activated to coordinate activities with regard to respective tasks. Where the respective tasks require cooperative efforts of a plurality of controllers, the respective coordinators ensure cooperative efforts by generating and communicating cooperative commands to the plurality of controllers. The coordinators may act as clearinghouses for system data, selectively requesting and relaying system information to appropriate controllers. For example, a document processing system activates respective coordinators for respective sheets of print media. The respective coordinators orchestrate the transportation of the sheets by sequentially orchestrating the activities of sequentially selected pluralities of transportation actuator controllers. Selected sheet position information from sensors and/or from models maintained by the actuator controllers may be relayed by the coordinators to selected actuator controllers as appropriate to the sheet transportation tasks.

摘要： Controllers communicate commands in terms of goals and constraints. A goal is an objective. A constraint is information regarding how the goal is to be achieved. For example, a constraint may specify when, or how much of, a resource may be used to achieve a goal. Additionally, or alternatively, a constraint may specify an acceptable or expected accuracy or tolerance regarding how the goal is achieved. Each controller is expected to achieve assigned goals in accord with associated constraints. Thereby, system communication may be reduced. If controllers achieve goals according to specified constraints, the controllers do not need to provide updates or be updated regarding the status of activities of other controllers or regarding other operational context information. In some embodiments, commands are generally not acknowledged. Instead, serving controllers respond to a command with an error message if a goal cannot be met in accord with an associated constraint.
摘要翻译：控制器根据目标和限制来传达命令。目标是一个目标。约束是关于如何实现目标的信息。例如，约束可以指定资源何时或多少可用于实现目标。另外或者替代地，约束可以指定关于如何实现目标的可接受或预期的准确性或公差。预期每个控制器将根据相关约束实现分配的目标。由此，可以减少系统通信。如果控制器根据规定的约束实现目标，则控制器不需要提供有关其他控制器的活动状态或关于其他操作上下文信息的更新或更新。在一些实施例中，命令通常不被确认。相反，如果不符合关联约束的目标，则服务控制器对具有错误消息的命令进行响应。

摘要： A method for synchronizing the control efforts of a plurality of controllers includes determining an apply time for using updated information. The apply time can take into account worst case processing and/or communication delays across a system. Reacting to the updated information only after at the apply time ensures that all system elements are able to react to the updated information in concert. A time stamp indicates when the data was collected. The apply time indicates when the data can be used. Process modeling or simulation is used to estimate system status at the apply time based on the system status at the time of the time stamp, the updated information, and predetermined information regarding the behavior of the system over time. In a document processor, the method allows tightly coupled modules, such as sheet transportation modules, to behave in a cooperative manner when separate modules are in contact with the same sheet.
摘要翻译：用于同步多个控制器的控制努力的方法包括确定使用更新信息的应用时间。应用时间可以考虑到跨系统的最坏情况处理和/或通信延迟。仅在应用时间之后才响应更新的信息，确保所有系统元素能够对更新的信息进行协调一致的反应。时间戳表示数据何时收集。应用时间表示何时可以使用数据。过程建模或仿真用于根据时间戳，更新信息和系统随时间推移行为的预定信息，根据系统状态在适用时间估计系统状态。在文档处理器中，当单独的模块与相同的纸张接触时，该方法允许紧密耦合的模块（例如纸张传送模块）以协作的方式表现。
