Abstract— The purpose of the study is to investigate the tuning of parameter gain PID controller for a DC servo motor. In this research, comparison between the meta-heuristic algorithm of Multi-objective Whale Optimization Algorithm (MOWOA) and Multi-objective Grey Wolf Optimizer (MOGWO) for PID tuning are made. Three objective functions are employed i.e. minimal settling time (ts), minimal overshoot (MP), and minimal steady state error (ess). The MOWOA gives a better result based on the hypervolume indicator.
