An adaptive internal model control strategy for pH neutralization

Abstract An adaptive internal model control strategy that is capable of providing effective and robust control for pH neutralization has been developed. The approach is based on combining the concepts of non-linear internal model control, strong acid equivalent (Wright and Kravaris, 1991, Ind. Engng Chem. Res. 30 , 1561–1572) and a simplified adaptive mechanism (Huberman and Lumer, 1990, IEEE Trans. Circuits Systems 37 , 547–549). The resulting control system is extensively tested via simulation for acid-base neutralization. The results show the excellent capabilities of the proposed method for disturbance rejection, servo control and tolerance to model uncertainty.
