摘要：ABSTRACT- Continues Stirred Tank Reactor (CSTR) is an important subject in chemical process
and offering a diverse range of researches in the area of the chemical and control engineering.
Various control approaches have been applied on CSTR to control its parameters. This paper
presents two different control strategies based on the combination of a novel socio-political
optimization algorithm, called Imperialist Competitive Algorithm (ICA), and concept of the gain
scheduling performed by means of the least square and fuzzy logic approaches. The goal is to
control the temperature of the CSTR in presence of the set point changes. The works followed with
designing those controllers and simulating in MATLAB software. The performance of the proposed
controllers have been consider based on the Sum of the Square Error (SSE) and Integral Absolute Error(IAE) Criteria. The results clearly indicate that both suggested control strategies offer an
acceptable performance with respect to the functional changes of the process. In other word,
robustness of the proposed methods in dealing uncertainties throughout the tracking of the
reference signal take the highlighted point into account. Furthermore, fuzzy based structure
strategy gives the more flexibility and precise behavior in control action in comparison to the least
square based approach.
