<p>A PID controller node.</p>
|
|
<p>This node ONLY expects a numeric <code>msg.payload</code> containing the current reading.
|
|
It will output the correction that needs to be applied in order to move to the preset <i>set point</i> value.</p>
|
|
<p>See <a href="https://en.wikipedia.org/wiki/PID_controller" target="_new">Wikipedia</a> for more details.</p>
|
|
<p>The <i>set point</i> may be overridden by <code>msg.setpoint</code>. If you do so the edit box value can be used as the initial value.</p>
