Input-output scaling factors tuning of type-2 fuzzy PID controller using multi-objective optimization technique

<abstract><p>The PID controller is a popular that widely used in various industrial applications. On the other hand, control problems microgrids (MGs) are so challenging, because of natural disturbances such as wind speed changes, load variation, and changes sources. This paper proposes an input-output scaling factor tuning interval type-2 fuzzy (IT2F) using multi-objective optimization technique. The suggested applied to MG frequency regulation problem. In introduced effect variations renewable energies (REs) taken into account, robustness investigated. scheme, some factors least overshoot, minimum settling/rising time considered. simulations show by considering suitable adjustment desired accuracy achieved, trajectory shows time.</p></abstract>
