Abstract

This paper considers auto-tuning of simple lead-lag decoupler plus decentralized PI/PID controllers for effective control of two-input and two-output (TITO) processes. A new robust identification method from step tests is presented first for SISO processes and then sequentially applied to TITO processes. The resulting 1st-order plus dead-time model is used for decoupler design and the 2nd-order one is used for decentralized PID sequential tuning. The simulation is given for illustration of the proposed tuning.
