What are the basic elements of a system of automatic control?
If we reviewed the drawing shown in Figure 2 in Fsnlahz that there are four key elements of the department of any automated system can be broken down as follows:
• Measurement of measurement
• actuator final Final Actuator
• The Process process
• Automated ruling The Automatic controller
Here we will describe a simplified for each item separately:
Measurement Measurement
Output is measured to determine the present value of the variable that is controlled, such as pressure or temperature or level ...... etc. and uses the measuring device converts the value to the physical value of the electrical record Standard Values for the governor can deal with them examples of normative values or standard 0to 20 mA or 4-20 mA or 0-10v .... etc
Indicates the change in the electrical signal measured on the physical change in the value that people want to control.
And measurement is essential to complete the control must therefore be calibrated measuring device and not by any defect or else will be making decisions or actions of the ruling will not be telling the truth and lead to disorder and instability of the system.
Actuator final Final Actuator
Each process must be the final player Final actuator, a mechanical part, which is controlled electrically to the work of the organization or toning to change the value measured Feed Back signal to reach stability. Examples include servo drives and motors move .... etc.
