In a split range control loop, the output of a controller is split and sent to two or more control valves to control a process. The controller output is sequenced such that one valve controls when the output is 0-50% and the other valve controls when the output is 50-100%. An example is given of controlling hotwell level using a split range strategy with a recirculation valve controlling when the level is below 50% and a deaerator valve controlling when it is above 50%. The strategy allows effective control of a process using multiple final control elements with a single controller output.
The document discusses distributed control systems (DCS), including their evolution, architecture, components, and applications in power plants. A DCS decentralizes control of an entire plant or manufacturing system across multiple controllers that communicate with each other. It allows for monitoring and control of all processes, identification of faults, and improved safety. A typical DCS architecture includes servers to collect and share data, archives for data storage, operator stations to monitor processes and alarms, engineering stations to configure the system, master controllers to supervise devices and modules, and field devices where the actual processes take place. DCS systems are hierarchical with lower-level controllers handling basic functions and higher-level controllers coordinating plant-wide control.
The document discusses control system trends and different distributed control system (DCS) architectures. It describes the evolution of DCS from centralized to distributed control with fieldbus connectivity. It provides examples of DCS installations and components of DCS systems from manufacturers like Honeywell, Yokogawa, and ABB. These include control stations, input/output modules, networks, and the use of Windows-based control.
This document provides information about programmable logic controllers (PLCs). It discusses what a PLC is, its applications in machine control and process control, advantages like speed and cost effectiveness. It describes PLC types based on memory and I/O range. The core components of a PLC are described including the central processing unit, input/output modules, power supply and bus system. Programming standards for PLCs like IEC 61131-3 are also mentioned. Selection criteria for PLCs versus distributed control systems includes factors like cost, reliability, flexibility and standard compliance.

http://shrutizpresentations.blogspot.in/2014/04/plc-ladder-diagram-basics.html
This document discusses override control systems. An override control system allows one controller to override another by selecting the most critical process value. It describes a system that uses override control to protect a water pump. A level controller overrides a pressure controller to slow the pump speed if the well level drops too low, preventing the pump from running dry while still maintaining some water pressure. This provides a "soft constraint" with moderated action as well as a backup "hard constraint" shutdown for additional safety. Integral windup must be managed when controllers are overridden to prevent control issues.
Industrial automation systems use control systems like computers and robots to replace humans in industrial processes. There are three main types of industrial automation systems: fixed automation systems which use dedicated equipment for specific tasks; programmable automation systems which can be reprogrammed for different batches; and flexible automation systems which are computer-controlled and can change tasks without retooling. Industrial automation provides benefits like reduced costs, higher quality and accuracy, and increased efficiency and safety, but also has disadvantages such as high investment costs and potential job losses.
The document discusses the development of control systems from manual to PLC control. It provides details on traditional control devices like relays, contactors, and motor starters. It then describes the different types of control systems including PLC, DCS, and PC-based controls. The remainder of the document focuses on PLC systems, their components, functions, advantages, disadvantages and applications in industries like food processing. It also discusses the history and development of PLCs and lists some major PLC brands.

continue regelaars
W - X = groot ==> aan-uit
W - X = klein ==> fijnere regeling
voordelen:
- bruikbaar bij snel veranderende en complexe processen
- bruikbaar wanneer hoge nauwkeurigheid vereist is
nadelen:
- complex
- duurder
soorten: P-, PI-, PD-, PID- en FUZZY-regelaar (zie later)

5 Verschil tussen sturen en regelen
REGELAAR
PROCES ACTUATOR
STORING
gewenste waarde W
regelwaarde Y
STURING
Bij een sturing is er geen terugkoppeling aanwezig.
Er is geen meetwaarde van een sensor voor de regelaar.
We spreken van een open kring.

6 Waarom automatisch regelen?
1 Technische redenen:
- wegwerken van storingen;
- vermijden van gevaarlijke situaties;
- complexe regelingen.
2 Economische redenen:
- hoge kwaliteitseisen;
- goedkopere productie, dan met mensen (handmatig regelen).
3 Sociale redenen:
- afstompend werk vermijden.
4 Veiligheidsredenen:
- machines maken geen fouten;
- machines bewaken meerdere factoren gelijktijdig en alarmeren snel.
5 Milieu redenen:
- minder energieverbruik;
- minder verlies aan grondstoffen.

Meettechniek handelt enkel over de sensoren die rapporteren aan de regelaar.
Regeltechniek omvat alle technologie en algoritme in de regelkring.
REGELAAR
SENSOR PROCES ACTUATOR
STORING
gewenste waarde W
gemeten waarde X
regelwaarde Y
Aan-uitregelaar schakelt aan wanneer de gemeten waarde onder de gewenste waarde komt en
schakelt uit wanneer de gemeten waarde boven de gewenste waarde komt.
De aan-uitregelaar is enkel bruikbaar voor trage onnauwkeurige processen
Continue regelaar gedraagt zich als aan-uitregelaar, totdat de gemeten waarde in de
proportionele band valt en schakelt dan over naar een fijnere regeling.
De continue regelaar is bruikbaar voor snelle en nauwkeurige processen, maar duur en complex.
Sturing heeft geen terugkoppeling van een sensor (open kring)
Regeling heeft een handmatige/automatische terugkoppeling (gesloten kring)
Automatisch regelen heeft de voorkeur omwille van technische; economische; sociale;
veiligheids- en milieuredenen.
