Variable-order fraction chaotic systems with finite-time adaptive sliding mode synchronization
The synchronization problem of variable-order fractional third-order cubic chaotic system with reduced controller was studied. By using variable-fractional-order stability theory and finite-time adaptive sliding mode synchronization correlation conclusions, sliding mode function and variable- order fractional adaptive laws were designed to obtain the conditions of finite-time sliding mode synchronization. For the third-order system, only two controllers were designed to achieve adaptive sliding mode synchronization between the master and slave systems of the variable-order fractional third-order cubic chaotic system in finite time, thus reducing the number of controllers. Numerical simulations verified the correctness of the conclusion.
