Autotuner identification of TITO systems using a single relay feedback experiment

Berner, Josefin LU ; Soltesz, Kristian LU ; Hägglund, Tore LU and Åström, Karl Johan LU (2017) 20th IFAC World Congress, 2017 In IFAC-PapersOnLine 50(1). p.6619-6623
Abstract
Relay autotuning has proven very successful for single-input single-output systems. This paper proposes an identification method for relay autotuning of systems with two inputs and two outputs (TITO systems). The combination of asymmetric relay feedback and output error identification admits short tuning time, without the need for limit cycle convergence. The method is successfully demonstrated on relevant system models, including the Wood-Berry distillation column.
