Series PID controller tuning based on the SIMC rule and signal filtering 2014 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/2/2859 http://www.sciencedirect.com/science/article/pii/S095915241300200X M. Mataušek B. Jevtović I. Jovanov The SIMC (Simple control) rule, proposed by Skogestad, is ineffective for a class of processes with oscillatory dynamics and processes defined by transfer functions obtained as a result of ideal decoupling of multiple-input multiple-output systems. For this class of stable processes it is proposed to apply a higher-order filtering to the open-loop process step response and to approximate the filtered step response with stable SOPDT models. These models are used to obtain a high performance/robustness tradeoff by the ideal series PID controllers, tuned by the SIMC rule, with the higher-order filter in the feedback loop. Parallel PID controllers, with higher-order noise filters, tuned by applying exact process frequency response and optimization under constraints on the robustness and sensitivity to measurement noise, are used to demonstrate merits of the proposed simple design and tuning of the series PID controller. Experimental results on a mechanical laboratory plant are presented in Appendix. article 10.1016/j.procont.2013.10.001 24 5 687 693 0959-1524 JOURNAL OF PROCESS CONTROL
