【正文】 for direct control of the production process, for PID, or feedforward control。 and then develop control programs, the output control instruction, operator reference control instructions manually controlled operation to control parts of the object or subject control process control. This control form is called offline puter control system. 5, realtime control system control puter realtime control system is 安徽理工大學(xué) 畢業(yè)設(shè)計(jì) 3 controlled by the control of the object or process, or request when the request processing control, the control function in a timely manner to address and control systems, monly used in the production process is interrupted for the occasion. Such as steel, each one refining furnace steel is a process。 中英文翻譯 安徽理工大學(xué) 畢業(yè)設(shè)計(jì) 2 Classification of control systems there are three ways: by automatic classification methods in order to participate in the control mode classification, to adjust the law category. One way to control category 1, the openloop control system if the puter output of open loop control system to exercise control of the production process, but the control results the state of the production process does not affect the puter control systems, puter \ controller \ production and other sectors does not constitute a closed loop, is called openloop control system puter. the production process of the state is no feedback to the puter, but by the operator to monitor the status of the production process, decision control program, and tell the puter to control the role of exercising control. 2, closed loop control system puter to the production of an object or process control, the state can directly influence the production process puter control system, called the closedloop control system puter. Control of the puter monitor in the operator, the automatic acceptance of the production process state test results, calculate and determine the control scheme, the direct mand and control units (devices) of action, the role of exercising control of the production process. In such systems, aircraft control ponents under control of control information sent to control device operation, the other running equipment condition as the output, measured by the detection part, the feedback as input to the control puter。 to make control Computer \ Control Components \ production \ test ponents form a closed loop. We will call this form of control puter control closedloop control. Closed loop control system puter, using a mathematical model to set the value of the production process and test results of the best value of the deviation between the feedback and control the production process to run at their best. 3, line control system as long as the puter controlled production of the controlled object or process, to exercise direct control, without human intervention are called the control puter online control, or online control system. 4, offline control system control puter does not directly participate in the control object or the controlled production process. It only managed to plete the process of the controlled object or the status of testing, and testing of data processing。 and if the process rolling, rolling out each piece of steel considered a process, each process is repeated. Only enter the process only requires a puter control. Once control of the puter, it requires a puter from the production process information in the require
