OPTIMIZATION OF PID CONTROLLER USING THE MULTI-OBJECTIVE EVOLUTIONARY ALGORITHM BASED ON DECOMPOSITION

Abstract

In control system design, controller parameters need to be adjusted for the controller to show optimum performance. This is usually achieved by solving a “Multi-Objective Optimization Problem” (MOP). In this study, “Proportionality-Integral-Derivative” (PID) controller is considered as the controller and the optimization of the performance objectives selected as the overshoot and rise times of the controller is performed. Although it is possible to adjust the PID parameters by using “Evolutionary Algorithms” (EAs) belonging to the class of population-based optimization algorithms, the computational load of EAs increases when diversity and eliteness are considered for the found solutions. For this reason, an algorithm known as “Decomposition-Based Multi-Objective Evolutionary Algorithm” (MOEA/D) has been preferred instead of EAs for the solution of the optimization problem. With this algorithm, the MOP is addressed by decomposing it into a certain number of single-objective sub-problems over scalarization functions based on the Tchebycheff decomposition. Therefore, instead of a single optimum solution, a set of “Pareto Optimal” (PO) solutions is reached. In this study, the performances of the DC-DC buck converter were evaluated using PID controllers with PO parameter sets obtained with the help of MOEA/D.
