Authors Contributions

: Mr. Putta Vihari has worked to obtain the data for the case study considered. Accordingly, the controller design methodology is decided upon. Second Author, Dr. C. V. Nageswara Rao took up the simulation study using a Simulation tool while training the first author. A method of RNGA based controller design is utilized based on the brainstorming discussion among the authors. As there are few research works which addressed non-square systems this methodology is adopted. Mostly PI controller would suffice maximum variables to control and hence design of PI controller.
