MODEL-FREE OUTPUT FEEDBACK CONTROLLER DESIGN FOR TWIN ROTOR SYSTEMS

Abstract

In this work, tracking control of twin rotor systems is aimed. The control problem is restricted by the lack of mathematical model of the twin rotor and further complicated by the unavailability of the angular velocity measurements. A model–free controller in conjunction with a high gain observer is designed. Experiments performed on a twin rotor system demonstrates the viability of the controller–observer couple.
