Indices expressing setpoint tracking and disturbance compensation and stability margin (robustness) are calculated. From these indices and a personal impression about how quick a method is to deliver the tuning result and how simple it is to use, a winning method is identified. %K PI tuning %K air heater %K Skogestad's method %K Ziegler-Nichols' methods %K Haegglund and Astrom's method %K Tyreus-Luyben's method %K Relay method %K Setpoint Overshoot method %U http://www.mic-journal.no/PDF/2010/MIC-2010-3-1.pdf
