WIND GUSTS COMPENSATION ACTING ON AN AUTONOMOUS HELICOPTER USING VARIABLE STRUCTURE DIFFERENTIATION SCHEME

This paper deals with the problem of disturbance reconstruction acting on an autonomous helicopter. The disturbance consists in wind gusts, the objective, which is original in this context, being to estimate it by using differentiation of the measurements, in order to compensate these disturbances and to improve the performances of the control. Two differentiation variable structure based strategies are used and compared in term of control performances.
