1	Robustness versus performance tradeoffs in PID tuning Amiri, Mohammad Sadegh 11 1900 (has links) Proportional, integral and derivative (PID) controller tuning guidelines in process industry have been in place for over six decades. Nevertheless despite their long design history PID tuning has remained an ‘art’ and no single comprehensive solution yet exists. In this study various considerations, with new and different perspectives, have been taken into account in PID tuning design. This study explores the issue of PID tuning from a practical point of view with particular focus on robust design in the presence of typical problems in process industry: process changes, valve stiction effects and unmeasured disturbances. The IMC tuning rule is recommended for setpoint tracking, while in the case of regulation, a newly proposed tuning rule, based on a combination of IMC and Ziegler-Nichols method, is demonstrated to give satisfactory results. The results were evaluated by simulation and were also validated on a computer-interfaced pilot scale continuous stirred tank heater (CSTH) process. / Chemical Engineering PID controller tuning Process control Robustness and Performance tradeoff ZNIMC tuning rule TUNIX simulation package Valve stiction Model plant mismatch (MPM) Servo and regulatory control Process abnormality Negative derivative action OPC setpoint tracking disturbance rejection
