PID Boost Contorl States


Conditions

PV (Process variable) can be MAP (note: all capital) or boost

1. PV appr. equals target // no change in PWM

2. PV below target // build boost raise PWM

3. PV above target // bleed boost lower PWM

if (boost != wanted_boost)// boost is not perfect

{

if (boost < wanted_boost)//build boost

...

if (boost > wanted_boost)//bleed boost

...

}

Now use the PID feedback to the PWM ..maybe?
