A control system is a system of devices that manages, commands, directs, or regulates the behavior of other devices or a system to realize a desired result. There are two varieties of system: 1) Open loop or non-feedback system and 2) Close loop or feedback system.
1) Open loop or non-feedback system: – It is a form of system within which the output system relies on the input but if the controller is independent of the output of the system it’s called open loop control system. This system doesn’t contain any feedback that’s why it’s referred to as a non-feedback system.
2) Closed loop or feedback system: – It is a kind of control system within which the output has an impact on the input quantity will adjust itself to support the output generated which is solely called closed loop control system.
Why will we need a control system?
Control systems are considered in concert of the most important aspects of our growing technology. Every sector of the industry is linked with the system in some or the opposite way. Everything is required to be controlled like in space technology, power installation, machine controlling, etc.
Advantage / Benefits of control system; –
Some advantage of system are as follows:
1) Power amplification
3) Convenience of input form
4) Compensation for disturbances.
A system can produce the needed power amplification or power gain-Robots designed by control system principles can catch up or atone for human disabilities.
System designs for diagnostics, heating and current drive have many similarities. System engineering methodology has been defined and is supported through templates and examples. Enterprise Architect used as the principal tool. Supports automated document generation.
