The physical and chemical properties of practical pH processes are usually not exactly known. Sophisticated adaptive pH control methods that are based on explicit process models are vulnerable to model uncertainties and their implementation in practi

A physical continuous flow process of unknown structure is identified under constant and variable flow rates by testing it in a well instrumented laboratory enviroment. The pH numbers of its input and output streams are measured continuously, convert
