Comparison of Different Performance Index Factor for ABC-PID Controller

Design optimization could be very challenging partially due to complexity and non-linearity of the system in consideration. Conventional methods are limited merely to certain operational zones and have unsatisfactory design robustness property. Metaheuristic algorithms are becoming increasingly popular among control engineers. Over the last two decades ,several meta-heuristic algorithms have emerged for the optimization of PID controller .These algorithms are faster in convergence and optimize globally(unlike conventional methods).In this paper ,one such algorithm known as Artificial Bee Colony(ABC) Algorithm has been proposed to tune the parameters of PID controller in order to optimize the system .A comparative study of the system is done for different performance index i.e. IAE,ISE and ITAE .
