Abstract
The inherent nonlinearity of the pH process often renders conventional control difficult. This non-linearity does however suggests that pH control would be a suitable application area for a fuzzy control system, whose ability to handle non-linearities is well known. Many fuzzy controllers are of the rule based type where the controllers output response is described by a series of control rules. However, the controller described in this paper is of a fuzzy-model based type which means that a fuzzy model of the process itself is embedded into the predictive control structure. Current work presents the performance of a fuzzy-model based pH controller for a strong base-weak acid neutralisation carried out in a constant volume CSTR. The performance of the fuzzy-model based controller is tested for various set points on the neutralisation curve.
