Multiswitching hybrid synchronization using disturbance observer adaptive sliding mode control on fractional order chaotic system

In this manuscript we have analysed identical financial systems of fractional order with external disturbances taken into consideration and introduced the disturbance observer to estimate the disturbance. We have applied adaptive sliding mode technique to synchronize these identical systems. Numerical simulations have been performed in MATLAB to validate the effectiveness of the method proposed. The obtained results show the usefulness and suitability of the method used to achieve the synchronization. A comparison has been made between the obtained and published results and application in secure communication has also been displayed.
