103 On the Construction of Embedded pH Process Automatic Control System Available to Purchase

The development and application of embedded system is remarkable in modern information society, which has been widely used in fields of every kind. The process of pH is widely applied in such industries as chemical engineering, bioengineering, wastewater treatment engineering and a generating station, so it is of great importance to have this process under good control. Owing to such features of the PH process as nonlinear and hysteresis quality, the test and control of the process seem not easy. This paper presents the application and construction of embedded technology in ph process with nonlinear control on the basis of feedback linearization.
