Abstract: Research work done in this thesis is motivated by the growing interest among control research community towards performance monitoring of control loops. A method that uses closed loop experimental data to determine the maximum control loop performance achievable with a PID type controller has also been described. A method to calculate the PI achievable targets for the process with recycle is described. A scheme is presented to systematically improve the control performance for process with recycles. A systematic way for tuning PID type controllers has been described. This method uses closed loop experimental data to determine the optimum controller settings for a PID type controller. An application of multi-objective evolutionary algorithm on generation of optimal Pareto decision curve for controller tuning was presented. It was shown that MOEA is very strong tool for generating optimal solutions to process control problems.
