Observer-based robust control for singular switched fractional order systems subject to actuator saturation

作者：

Highlights：

• The robust stabilization criteria for singular switched FOS subject to actuator saturation under the designed switching law is proposed.

• An observer to stabilize the closed-loop singular switched FOS is designed and the observer and controller gains are obtained.

• The stability region by solving an optimization problem in terms of LMIs is estimated.

• The presented methods are illustrated by the practical and numerical simulations.
