Adaptive PI Controller Design and Deployment for Chemical Reactor

In various food and chemical industries, chemical reactors are used for treating various reactants to get the desired product composition chemically. Such chemical reactors are having nonlinear and time-varying characteristics. This makes the job of control engineer difficult one and paved a way for continuous research in the field of chemical reactor control. The control various parameters like concentration of chemical species, pH, temperature, and reactant level are challenging aspects in the chemical reactor applications. This leads to the requirement of adaptive controller design and deployment strategies like the implementation of the Adaptive Proportional Integral (PD Controller. In this work, an adaptive PI Controller recursive polynomial model estimator is designed and deployed for the chemical reactor to maintain the pH of the product and level of reactant. The simulation results show the performance of the implemented Adaptive PI controller in terms of error criterion ISE, IAE and time domain specifications peak overshoot and settling time.
