A fuzzy controller for a multi-tank system

Abstract

Many processes encountered in practice are either too complex (being for example non-linear and multivariable) or too ill-defined to obtain controllers using classical control theory. A lack of system information and the need to provide simple effective solutions has lead to the development and trial of a fuzzy system controller for many ill defined processes. Without any detailed mathematical knowledge of the system apart from a basic human understanding of the process, a fuzzy controller was easily designed for a practical multi-tank system and the results demonstrate the power of the approach.
