What is a PID and PLC controller?

A PID (Proportional, Integral, Derivative) controller is a control loop mechanism that continuously calculates an error value as the difference between a desired setpoint and a measured process variable. It applies a correction based on proportional, integral, and derivative terms to minimise the error and stabilise the process. A PLC (Programmable Logic Controller) is an […]

What are the 3 main components of PID controllers?

The three main components of a PID (Proportional, Integral, Derivative) controller are: Proportional (P) component: Adjusts the output proportionally to the error, where the error is the difference between the setpoint and the process variable. It addresses the current error. Integral (I) component: Accumulates past errors and integrates them over time to eliminate residual steady-state […]
