This paper is concerned with an uncertainty and disturbance estimator-based tracking control problem for a class of interval type-2 fractional-order Takagi-Sugeno fuzzy systems subject to time-varying delays. The footprints the underlying are taken into account capture model different levels uncertainties. estimator used promote behavior rejecting in system. First, by applying Lyapunov approach...

This paper describes the simple Internet tool for fractional order pole models the Java applet free accessible on www.PIDlab.com. The applet implements procedures described in the authors’ previous works, where the value set approach to fractional order pole systems was presented for the case, when following characteristic numbers of the process were obtained: a) one sample of the process frequ...

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...

in recent years, there has been greater attempt to find numerical solutions of differential equations using wavelet's methods. the following method is based on vector forms of haar-wavelet functions. in this paper, we will introduce one dimensional haar-wavelet functions and the haar-wavelet operational matrices of the fractional order integration. also the haar-wavelet operational matrice...
