PID Control of Boost -------------------------------------- PID Theory and Tuning Links :MembersPage/NickLaTech/PIDTheroyandTune ------- PID Tuning Method 1 :MembersPage/NickLaTech/PIDTuneMethod1 ------ PID VS Boost graphs :MembersPage/NickLaTech/PIDvsBoostGraphs --------------------------------------- Fail Solutions :MembersPage/NickLaTech/PastSolutions ---------------------------------------- Dave_24's idea/explainantion on the subject :MembersPage/NickLaTech/DaveExplain ---------------------------------------- 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?
