(Askeri) ZİNCİRLEME KONTROL DEVRESİ (HV.): Nihayetsiz bir zincir meydana getirecek şekilde kimyasal bir tepkime ile bağlanmış: otomatik kontrol cihazları sistemi kontrol edilen miktarların ölçüyü aşması halinde, kontrol cihazlarının, bunu normale getirmek üzere harekete geçmeleri için kontrol hareketlerinin etkileri devamlı olarak ölçülür
closed-loop teriminin İngilizce İngilizce sözlükte anlamı
A system that uses feedback information to regulate the output response The output feeds back to a controller for comparison to the input command; any difference results in a corresponding change in the input command Thus, the accuracy increases
A system in which the output is compared to the command with the result being used to force the output to follow the command Servo systems are closed-loop
describes a system where a measured output value is compared to a desired input value and corrected accordingly (e g , a servomotor system)
(Ticaret) The system extending the original single function of material requirements planning (MRP) by including higher-level, long term production planning, master production scheduling (MPS), capacity requirements planning (CRP), production control and purchasing. Where the original MRP function strictly generated a materials plan by exploding bills of material, closed-loop MRP creates feedback and interaction by measuring the proposed material plan against longer term production and sales goals, verifying that capacity is available to complete the proposed production, and incorporating date and quantity changes to original plans required by vendors or the production floor
A system or piece of computer code in which every step in a control mechanism is contained inside the system, and does not utilize external input See also Feedback
refers to an advanced version of the Dichromat colour heads in which the system automatically detects and corrects for changes in the colour and intensity of the lamps, and movement of the filters is microprocessor controlled This system provides highly accurate filtration settings and maximum print repeatability through lamp changes and when working from recorded exposure data The need for fewer test prints ensures greater productivity
An underground heat exchanger piping system usually of polyethelene or polybutylene designed to allow the extraction or rejection of heat to the earth by the circulation of fluid within the tubing
A method of designing a control or guidance system in which all the elements (sensors, computers, actuators, etc ) are linked in such a way as to operate continuously with feedback between the elements The guidance systems for Apollo spacecraft were closed loop systems
A system in which each component is connected to the next component with the last component being connected to the original device Forms a complete circle
An operating mode of the PCM enabling modification of pre-programmed instructions based on a feedback system By constant exhaust sampling, a closed loop system allows pre-programmed engine adjustments to occur while running in order to minimize exhaust emissions
A regulator circuit in which the actual value of the controlled variable (such as pressure, temperature or speed) is sensed and a signal proportional to this value (feedback signal) is compared with a signal proportional to the desired value (set point signal) The difference between these signals (error signal) causes the controlling device to change in the direction that will reduce the difference in signals to zero
