PROCESS FLOW CONTROL SYSTEMAn improved method for automatically controlling the rate of mass flow in a system having a mass mover powered by a power supply which is attenuated by a control device for transferring mass through a conduit, wherein a signal proportional to said mass flow is ...
the director of engineering assigns you the task of designing an improved control system using a microprocessor. You perform a design study (using, for example, the methods of this book) and determine that a microprocessor-based controller
The purpose of this study is to compare the performance of various proportional, integral and derivative controller tuning methods for flow control system. A Tangent Method and Reformulation Tangent Method were compared in this paper to perform the open-loop test. From the open-loop test, the ...
To control the flow of air into and/or out of a process chamber, such as a clean room, a two-stage system is disposed in conduits leading into and/or out of the process-chamber. One stage includes a regulator, having a plenum (7, 79) disposed between the environment and the air sou...

监控,和仿真各个⽅⾯。相较于⼯作流,它更属于是管理和组 织的概念;⽽⼯作流则侧重技术层⾯的实施和运⾏业务流程。从这种⾓度看,⼯作流可以说是业务流程管理的⼦集。基于这两个 概念,现在有⼯作流管理系统(Workflow Management System)和业务过程管理系统(Business Process Management ...
