Design of fuzzy modified model reference adaptive controller for coupled tank process

Abstract

Flow control and level control has always been key issues in chemical process industries since many years. In this paper we have applied a model reference adaptive control (MRAC) technique to nonlinear level process. The MRAC design with good transient as well as steady state response is a challenging task. This paper examines the design of a Fuzzy Modified MRAC controller for nonlinear coupled tank process to obtain improved transient response along with good steady state response. The simulation results obtained by MATLAB shows that proposed design technique gives improved transient response than MRAC technique.
