In this paper, a robust tracking control method for automatic take-off and trajectory tracking of a quadrotor helicopter is presented. The designed controller includes two parts: a position controller and an attitude controller. The attitude controller is designed by using the sliding mode control (SMC) method to track the desired pitch and roll angles, which are the output of position controll...

This paper analyzes several properties linked to the robust control of fractional diier-ential systems with delays. The BIBO stability of both retarded and neutral fractional delay systems is characterized in terms of the location of their poles. In the particular case of retarded systems, we give some properties of the poles of the system and the singular values of its Hankel operator, as well...

Given experimental data and a priori assumptions on nominalmodel and a linear fractional transformation uncertainty structure, feasible conditions for model validation is given. All unknown but bounded exogenous inputs are assumed to occur at the plant outputs. With the satisfaction of the feasible conditions for model validation, it is shown that a parameterization of all model validating sets...

M.M. Share Pasand, H.D. Taghirad Abstract— The problem of model based internal control of singular systems is investigated and the limitations of directly extending the control schemes for normal systems to singular ones were analyzed in this paper. A robust approach is proposed in order to establish the control scheme for singular systems, and moreover, to present a framework for robust contro...
