Abstract
This paper offers an H-infinity (H∞) controller-based disturbance rejection along with the utilization of the water wave optimization (WWO) algorithm. H∞ controller is used to synthesize the guaranteed performance of certain applications as well as it provides maximum gain at any situation. The proposed work focuses on the conflicts of continuous stirred-tank reactor (CSTR) such as variation in temperature and product concentration. The elimination of these issues is performed with the help of the WWO algorithm along with the controller operation. In general, the algorithmic framework of WWO algorithm is simple, and easy to implement with a small-size population and only a few control parameters. The planned work gives the enhanced performance by means of disturbance rejection when compared with the PID, ADRC and ANN controllers. Additionally, the proposed work improves the lifespan of the offered application through the elimination disorders. The overall process is implemented in the MATLAB working platform and the results are compared with the preceding methods to show the expected performance.

Summary
H∞ methods are the type of control theory used to stabilize the performance of controllers through synthesizing the corresponding compensator. Controller feedback design method with disturbance as the constraint This control is applied to the continuous stirred-tank reactor analysis. According to Eq (5), controller K could be obtained by using γ-iteration, which involves an internal optimization process that is capable of minimizing the H-infinity norm of Tzw. 2.2 Continuous Stirred-Tank Reactor (CSTR) CSTR is one type of reactor in chemical engineering field in which temperature control can be considered as a major issue. 2.2 Continuous Stirred-Tank Reactor (CSTR) CSTR is one type of reactor in chemical engineering field in which temperature control can be considered as a major issue This kind of difficulty is eliminated through the utilization of optimizationbased H∞ controller with feedback design method.
