Analytical PI Controller Tuning Using Closed-loop Setpoint Response

Recently Shamsuzzoha and Skogestad proposed a proportional-integral (PI) tuning rule for a wide range of unidentified processes. The rule relies on a closed-loop setpoint response (CSR) of a process and was developed from extensive numerical experiments. This work analytically derives a similar PI tuning rule using the CSR method. Simulations indicate that the two rules perform similarly if the...
