Abstract :
The tracking control of a twin-lift helicopter system in the presence of parametric uncertainty is considered. A nonlinear model is used to describe the dynamics of a twin-lift helicopter configuration in the lateral/vertical plane, and a controller is synthesized using an input-output feedback linearization technique in conjunction with an adaptation algorithm. The control scheme does not require any knowledge of the bound of uncertainties present and drives the output tracking error to zero asymptotically. The performance of the controller is illustrated by simulating the nonlinear model of the twin-lift system.<>
