Abstract

Coefficient Diagram Method (CDM) based PI controllers (CDM-PI and CDM-PI-P) has been implemented in a <i style="mso-bidi-font-style:normal">p</i>H neutralization system to control the <i style="mso-bidi-font-style:normal">p</i>H value of industrial effluent. The proposed techniques are tested with collected effluent in lab-scale <i style="mso-bidi-font-style:normal">p</i>H neutralization system. Experimental runs are carried out at the operating point of <i style="mso-bidi-font-style: normal">p</i>H 8 as per the requirement of PCETP and the regulatory performance in terms of Error Indices (ISE and IAE) and Total variations (TV) are reported. The results of the proposed control techniques are compared with conventional control techniques such as Ziegler Nichols PI controller (ZN-PI) and Internal Model Control based PI controller (IMC-PI). The experimental results show that the proposed CDM based PI controllers had impeccable performance with industrial effluent in <i style="mso-bidi-font-style: normal">p</i>H neutralization system.
