Adaptive fuzzy control for chemical continuous stirred tank reactor system with dead zone input

This paper presents the flexible adaptive fuzzy control method for chemical continuous stirred tank reactor, one of uncertain nonlinear systems. Objects of this method include input dead zone observed when controlling valve or motor current in practice. Adaptive fuzzy logic system is used to approximate the nonlinear systems. Compared with the previous method, this adaptive fuzzy control approximation is more flexible, so can be extened to the chemical continuous stirred tank reactor with dead zone of valve input control. So, this work observe chemical continuous stirred tank reactor (CSTR) system which can be extended to one with dead zone input and design the adaptive fuzzy controller of this system is designed. Finnaly, the validity of the proposed control method is tested with chemical continuous stirred tank reactor (CSTR) with dead zone input.
