[Harvs] hacked a cheap PID controller he found ... this meant the controller was assuming the cold junction was at room temperature, and would in many cases be significantly inaccurate.

In order to achieve similar results, [Aaron] instead created a PID controller that uses temperature feedback ... accurate to 0.5°C (0.9°F). From the pictures it looks like [Aaron] has finally ...

For example, a temperature sensor positioned a long distance from a heater can slow response to dynamic changes. Changes in machines and processes due to disturbances and set point changes are why PID ...

But in many instances, no amount of adjustment of the proportional-integral-derivative (PID) parameters will ... installed gain to replace the control valves. The cascade control system in figure 5 ...
