Monotonic, Minimum-Settling-Time PI Tuning for First-Order-Plus-Dead-Time Plants: A Tangency Characterization
Senol Gulgonul
This paper studies PI tuning of a first-order-plus-dead-time (FOTD) plant for the fastest strictly monotone (zero-overshoot) setpoint step response, with monotonicity imposed on th…
Minimum settling-time PI control of pure delay processes under a hard non-overshoot constraint: exact boundary-contact characterization and the role of the MID point
Senol Gulgonul
We solve, exactly, the problem of minimum settling-time PI control of a pure delay process K e^{-Ls} under the hard time-domain constraint of zero overshoot, y(t) <= 1 for all t. T…
Closed-Form PI and PID Tuning of All-Pole Plants up to Third Order for Monotonic Minimum-Settling Step Responses
Senol Gulgonul
A unified, closed-form analytical PI/PID tuning method is presented for all-pole plants up to third order that yields a strictly monotonic (zero-overshoot) step response with minim…
PID Tuning via Desired Step Response Curve Fitting
Senol Gulgonul
This paper presents a PID tuning method based on step response curve fitting (PID-SRCF) that utilizes L2-norm minimization for precise reference tracking and explicit transient res…
