In this study, a robust control technique is investigated for the reference tracking of uncertain
time-delayed systems in the existence of the actuator saturation. Due to emerging of some …

This paper presents a unified framework for exponential stability analysis of linear stationary
systems with irrational transfer functions in the space of an arbitrary number of unknown …

This paper investigates the stabilization of uncertain neutral-type delay fractional systems.
Both static and dynamic output feedback control design methods are proposed. A …

Time delay in actuators is mainly caused by electrical and mechanical components. The
effect is visible in the system response particularly when changing in the input command …

This paper proposes a barrier function-based adaptive control strategy with a nonlinear
sliding surface for a class of uncertain dynamic systems with input saturation. Its main …

This brief focuses on the stability and stabilization of variable fractional-order neutral
systems (VFONS) with time-varying delays and time-varying structured uncertainties. Via the …

This paper concentrates on the sliding mode H∞ control for variable fractional order
uncertain differential systems with time-varying delay and external disturbance by using the …

In this paper, an optimisation method utilising the yellow saddle goatfish algorithm (YSGA)
with a new fitness function is proposed to design two types of fractional-variable-order PID …

This work addresses the stabilization of variable fractional-order (VFO) neutral-type systems
with structure perturbations and unknown disturbance signals using the feedback control …

This work discuss the stabilization issue for a class of fractional-order nonlinear systems
together with time delay, parametric uncertainties and actuator faults. Precisely, the …
