What is PID Control?

Posted by Ian Parnell in on 30 January 2014

PID stands for Proportional, Integral, Derivative.

PID control provides a continuous variation of output within a control loop feedback mechanism to accurately control the process, removing oscillation and increasing efficiency.

On-Off Control v. Proportional Control

Posted by Ian Parnell in on 28 January 2014

A proportional controller output isn’t just on or off. Its output can be adjusted to any value between 0% and 100% of power.

Just as with on-off control, the control direction is important. Reverse or inverse acting changes the output from 100% to 0% as the process rises if heating. Direct acting would go from 0% to 100% if cooling.

When correctly tuned, the controller can adjust its output to match the power that is required to keep the process stable at the setpoint. This is something an On-Off controller cannot achieve.
