PID for Dummies - Control Solutions

The PID controller looks at the setpoint and compares it with the actual value of the Process Variable (PV). Back in our house, the box of electronics that is the PID controller in our Heating and Cooling system looks at the value of the temperature sensor in the room and sees how close it is to 22°C. They do this in a PID loop by adding

A straightforward explanation of feedforward control

Jun 09, 2020 · Greg: The use of feedforward control is often a missed opportunity because of the misinformation in the literature and the lack of guidance on implementation. Here we get a straightforward understanding and approach to feedforward control from Peter Morgan, who as leader of the ISA 5.9 Standards and Practices (S&P) working group for PID algorithms is responsible for …

Superheaters - an overview | ScienceDirect Topics

This control loop is also considered one of the most important control loops in the thermal power plant instrumentation system. The saturated steam from the boiler drum is superheated by adding heat from various superheaters. Before the final superheaters (left and right sides), water spray chambers in the DSHs spray the hot feedwater as
