Experimental Verification of Lead-Lag Compensators on a Twin Rotor System

Meryem Deniz, Enver Tatlicioglu, Alper Bayrak


In this study, lag and lead type compensators are designed and then experimentally verified on the twin rotor system. Specifically, first, lag and lag-lag compensators are designed to obtain a reduced steady state error when compared with proportional controllers. Secondly, lead compensation is discussed to obtain a reduced overshoot. Finally, to make use of their favorable properties at the same time, lag-lead compensators are designed. All the compensators are applied to the twin rotor system in our laboratory.
