【Abstract】 Aiming at the finite time synchronization problem of incommensurate fractional order Genesio-Tesi systems with unknown disturbances and uncertainties, a new fractional order finite time disturbance observer is designed to estimate external unknown disturbances and uncertainties. A suitable fractional order sliding mode surface and corresponding adaptive sliding mode controller are constructed to achieve finite time adaptive sliding mode synchronization of fractional order Genesio-Tesi systems with different initial conditions. The MATLAB numerical simulation results show that the designed fractional order disturbance observer and adaptive sliding mode controller are effective and feasible.更多还原
