// PID Challenge - we have a small thermal mass that we to want heat up as fast as possible but we don't

// related to the sensor (thermocouple) or DAQ system, that otherwise are fairly decent. The real issue is
// the thermal inertia. We basically read the temperature in the window between two heating sessions when
// the output is off. However, the heater temperature does not dissipate instantly into the tip mass so
// at any moment right after heating, the thermocouple would sense a temperature significantly higher than
// moments later. We could use longer delays but that would slow the PID loop and that would lead to other
// negative side effects. As a result, we can only rely on the I term but with a twist. Instead of a simple
// integrator we are going to use a self decaying integrator that acts more like a dual I term / P term
// rather than a plain I term. Depending on the circumstances, like when the delta temperature is large,
// it acts more like a P term whereas on closing to setpoint it acts increasingly closer to a plain I term.
// So in a sense, we have a bit of both.
// So there we go...
// P = (Thermal Mass) x (Delta Temperature ) / 1sec, where thermal mass is in X10 J / °C and
// delta temperature is in °C. The result is the power in X10 W needed to raise (or decrease!) the
// tip temperature with (Delta Temperature ) °C in 1 second.
// Note on powerStore. On update, if the value is provided in X10 (W) units then inertia shall be provided
// in X10 (J / °C) units as well. Also, powerStore is updated with a gain of 2. Where this comes from: The actual
// power CMOS is controlled by TIM3->CTR1 (that is software modulated - on/off - by TIM2-CTR4 interrupts). However,
// TIM3->CTR1 is configured with a duty cycle of 50% so, in real, we get only 50% of the presumed power output
// so we basically double the need (gain = 2) to get what we want.
