Abstract: This paper proposes interval type 2 fuzzy proportional–integral–derivative controller plan technique and it is connected to the non-straight framework continuous stirred tank reactor. Interval type-2 fuzzy controller is composed such way that it is autonomous of process. To comprehend the impact of impression of uncertainty on the controller’s execution to two type of control bend to be specific forceful and smoother control bend are outlined. Popov-Lyapunov technique is utilized to discover stability of the framework.
Keywords: Interval type 2 fuzzy, continuous stirred tank reactor.
