Document Summary

2 sheets of notes (old one + 1) everything except semiemperical methods are on exam controller tuning is on exam (do something to get a certain time constant) Under what circumstances will it lead to or deviate from pid controller. Recall, you can always obtain this from the more general one by focusing on the measured output and the internal set point. Not sacrificing a lot to analyze this onewe ignore valve and measurement dynamics. Assumptions: degree of n < degree of d (proper, roots of d(s) are in the lhp --> gp is stableif not, we can stabilize with a proportional controller before we proceed. If (stable), then will guarantee closed loop stability. In this case, the closed-loop response will be. Then from the final value theorem, i have. For zero-offset, i need to have or static gain of q(s) = inverse of static gain of gp(s)
