Stability analysis of discrete-time fractional-order Caputo-type Lorenz system
Dorota Mozyrska , Małgorzata Wyrwas
AbstractIn this paper we study discrete-time fractional-order Lorenz systems. We use the Caputo-type h-difference operator with orders from the interval (0,1). Using conditions for asymptotic stability of linear systems with the Caputo fractional-order h-difference operators we made simulations with small steps h and checked wether there are unstable equilibrium points for the considered systems. We also investigate by numerical calculations in Maple that the generalised Lorenz systems have chaotic behaviour for step h = 0:01 and for order functions with values greater than 0.95645.
