作者：

Highlights：

• In this paper, we present a new fractional-order hyperchaotic memristor oscillator.

• The proposed system has been investigated through numerical simulations.

• A novel robust adaptive controller is implemented to synchronize the system.

• As an application, the system has been implemented for voice encryption.
