Input output controller

A process, or activity, can be defined as a transfer function with one or more inputs, outputs, controls, and resources that together all enable the variables to gain data and then fire. [Pg.176]

The basic setup to determine static interfacial tension based on either the Wilhelmy plate method or the du Noiiy ring method (see Alternate Protocol 2) is shown in Figure D3.6.1. It consists of a force (or pressure) transducer mounted in the top of the tensiometer. A small platinum (Wilhelmy) plate or (du Noiiy) ring can be hooked into the force transducer. The sample container, which in most cases is a simple glass beaker, is located on a pedestal beneath the plate/ring setup. The height of the pedestal can be manually or automatically increased or decreased so that the location of the interface of the fluid sample relative to the ring or plate can be adjusted. The tensiometer should preferably rest on vibration dampers so that external vibrations do not affect the sensitive force transducer. The force transducer and motor are connected to an input/output control box that can be used to transmit the recorded interfacial tension data to an external input device such as a monitor, printer, or computer. The steps outlined below describe measurement at a liquid/gas interface. For a liquid/liquid interface, see the modifications outlined in Alternate Protocol 1. Other variations of the standard Wilhelmy plate method exist (e.g., the inclined plate method), which can also be used to determine static interfacial tension values (see Table D3.6.1). [Pg.633]

Operating system Software controlling the execution of programs and providing services such as resource allocation, scheduling, input/output control, and data management. Usually, operating systems are predominantly software, but partial or complete hardware implementations are possible (ISO). [Pg.181]

The condition number is a measure of input-output controllability. If the condition number is small, then the multivariable effects of uncertainties are not likely to be... [Pg.487]

The methodology presented hereafter regards a MIMO system that can be handled by a combination of multi SISO loops. It is an input/output controllability being based on linear analysis tools. It can be applied to a stand-alone complex unit, as a distillation column, or to a flowsheet. In this later case it has the character of a decentralised (integral) plantwide control problem. [Pg.492]

Communication between workstation-computers and the other controlled elements of the system is conducted through new input/output controllers created by the Group HW [7] manufacturer, incorporating the possibility of communication using TCP/IP as Fig. 2 shows. [Pg.159]

In Figure 9.2, the shop floor control function is shown by the box labeled Production Activity Control. This is a short-range tracking function, which watches the progress of jobs through the shop, determines when to release more work (Input/Output Control), and determines the specific sequences of conducting work at the individual work centers. [Pg.129]

As its first contribution, IDEFO provides a good overview ofthe input, output, control, and mechanism objects within the supply chain operation aspect (see Figure 7). Using IDEFO, a process is presented to show what data or materials are consumed, what data or materials are produced, data that constrain or regulate the process, and also the resources (people, machines or systems) that carry out the process. [Pg.12]

IDEFO technique gives not only a good overview of input, output, control, and mechanism for each entity of the process, but also overviews the relationship between each entity linked by these objects. The relationships created by these links assist companies in identifying four types of interdependencies, which are listed below. [Pg.13]

IDEFO was selected to model SCOR business processes. The IDEFO technique has been found suitable for the purpose of describing SCOR processes in general when the flow of information and the independency relationships are to be considered. The IDEFO method has the potential to contribute additional aspects that are not represented in the current SCOR models, resulting in a more comprehensive representation of supply chain processes. IDEFO identifies the interdependency relationships in terms of input, output, control, andmechanism. This identification is very... [Pg.19]

Engell and co-workers in Chapter C4 deal with the control structure selection based on input/output controllability measures. The limitations imposed by non-minimum phase characteristics on the attainable closed-loop performance are considered in the evaluation of the candidate set of control structure configurations. The optimisation of the attainable performance over the set of all linear stabilizing controllers can refine the controller structure with input constraints and coupling properties directly accounted for. [Pg.6]

The alternative designs generated for the two test cases (heat exchanger and binary distillation) on basis of this TCA principle prove to be remarkably well aligned with the results of a black-box, input-output controllability analysis using the steady-state disturbance sensitivity approach. [Pg.166]

With input-output controllability of a process is here understood the inherent ability to achieve a desired control performance using available measurements and control inputs. See e.g., Sko-gestad and Postlethwaite [9]. The performance may be related to attenuation of disturbances and/or tracking of setpoint changes. [Pg.307]

In compact vector notation, the reactor model (Eq. 31) is given by the control system (1) with the following vectors and maps (Eq. 1) and input-output control structure (Eq. 2) ... [Pg.621]

HMI is the human to machine interface in a system. It is the operator interface or UI, which in modern systems is typically a computer screen with computer input-output controls for the operator. HMI is also the application of human factors and human engineering to system design to ensure the safe and reliable operation of the system throughout its life cycle. Since personnel are a major component of any system, special design consideration must be given to human performance. HMI is also sometimes referred to as MMI. HMI is identical to the more recent term HSI. [Pg.210]

Processes are the fundamental building blocks of a company s operations, and both the understanding and improvement in processes determine their excellence. Processes transform inputs (actions, methods, and operations) into outputs. They are the steps by which value is added to satisfy the expectations of customers. The processes interact with other processes in the supply chain, as outputs from one process form the inputs to another. Each process is therefore a part of a larger process so that an organization can be seen as a network of interconnected processes. In addition to the inputs and outputs, a process is defined by controls (a set of rules that determine how the process is to be performed), and the needed resources. Hence, we may describe a process as, process = /(inputs, outputs, controls, resources). [Pg.76]
