What is a PID Controller | Proportional Band | Integral Action | Derivative Action

Today we are going to discuss about pid(proportional band, integral, derivative)controller. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Video content: 1. What is Controller Modes, and what is controller responses to set point and process variable changes? What is controller modes? Controller modes is a function which defines proportional band function, the integral function, and derivative function for P Controller, P plus I controller, or P plus I plus D controller. Controller has three different modes. First mode is Proportional band gain. Second mode is Integral action. And third mode is Derivative action. Proportional Band(PB)- In P, I, D controller P stands for Proportional Band. It is proportional gain of controller, and its setting is within the PB module. This function is older terminology for controller gain. This function amplifies or attenuates the error signal, and the controller outputs a signal that is directly proportional this. Controller output= Gain*(PV - SP) GAIN = 1/%PB %PB = 100%/Gain The Gain function outputs a signal that is proportional to the size and shape of the error signal. Integral Action- This function also known as RESET action, and its setting is within the I module. It works as a function off time, to increase or decrease the controller Output at a rate that is proportional to the size of error signal, the difference between PV and SP, until the error signal is zero. Its output is the accumulated effect due to a persisting error signal and is proportional to that difference. The greater the error signal, the greater, the accumulated effect. Integral Time has units of minutes per repeat. When Ti is very large, COR becomes very small, virtually eliminating the effect of Integral Action. Its inverse is called Reset. This has units of Repeats per minute. Reset = 1/TI Derivative Action- It is Rate action of Controller, and its setting is within D module. This function operates on the rate of change, the slope, of the error signal. It has the effect of advancing the controller output response in time proportionally to the rate of change of the error signal. This function has units of minutes. The greater the slope of error signal, the greater the amplitude of the output signal. When Td is very small, COD also becomes very small, virtually eliminating the effect of Derivative Action. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ If you have missed our most recent videos, then watch them here: 1.
