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 ...
speed of response, tracking accuracy, disturbancerejection, stability margins), there may also be implicit requirements that are normally met by "conventional" control system designs. Being unaware of implicit
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 ...
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 ...
