Firstly, a stability boundary locus method is implemented to determine all stabilizing proportional integral (PI) controller gain that constitutes a stability region in the controller parameter space. A GA based optimization approach is then utilized to obtain an optimum set of controller gain that minimizes the mean square error of the deviation in the system frequency response. The effectiveness of the controller in retaining the desired frequency response is validated by time domain-simulation.eninfo:eu-repo/semantics/closedAccessConference Object768010.23919/eleco47770.2019.89904342-s2.0-85080953790N/AWOS:000552654100016N/A
