Second-order sliding mode control for nonlinear fractional-order systems

作者：

Highlights：

• An attempt is made to design LQR based SMC for nonlinear fractional-order systems.

• Fractional-order switching surface is used for attaining sliding mode dynamics.

• The suitable switching surface is designed for the nonlinear system and the SMC law is designed to ensure the stability of the system.
