PID Tunning Flashcards
What does PID stand for?
Proportional , integral , derivative.
What is a simple example of PID controller example?
Temperature and heating / air condition regulation at home.
What is the precondition or set value for PID
Setpoint point set
What is process variable?
Current variable or value at given time.
What is control variable?
Also known as manipulated variable, the modulator that contros action.
What is error?
Error is th difference between setpoint and process point.
What is disturbance
Factors or distribution that that can affect process variable meeting setpoint
Give example of control variable device?
Valve in hydraulic system .
Air conditioning unit in room heating cooling system
What parameters are used in PID?
Proportional
Proportional and Intregal
Proportional and derivative
Proportional Intregal and derivative
What devices are used for PID control?
Stand-alone and integrated PID controller are most commonly used.
How do you program PID loop using control logix or PIDE?
Use function block programming
Use for process control,
Integral control deals with accuracy but affected by time.
