This paper presents a review of the various control strategies that have been conducted to
address and resolve several challenges for a particular category of unmanned aerial …

This work presents design and theoretical analysis of an adaptive fractional-order sliding-
mode disturbance observer (FO-SM-DOB)-aided fractional-order robust controller for …

In this paper, an adaptive super twisting sliding mode controller (ASTSMC) is proposed for a
class of nonlinear systems to counteract mismatched uncertainties. To estimate the unknown …

This paper proposes a novel approach for designing the observer and controller for Takagi-
Sugeno (TS) fuzzy systems with an enlarged class of disturbances. The class of the …

Twin rotor systems in many ways resemble helicopters and they are multiple-input multiple-
output (MIMO) systems, highly nonlinear, and there is significant cross-coupling between …

In this study, a novel control design of nonlinear systems has been presented to solve the
problem of matched and unmatched perturbations (disturbances) with unknown upper …

Twin-rotor two-input two-output (TITO) aerodynamical system (TRAS) is a highly non-linear
system with a cross-coupling effect. The objective of the controller design in TRAS is to track …

This paper investigates a backstepping sliding mode fault-tolerant tracking control problem
for a hydro-turbine governing system with consideration of external disturbances, actuator …

A multi-axis gimbal tracking device is necessary for the micro spacecraft to detect the target.
The movement of the tracking device can generate a marked impact on its carrier in the …

This paper centers around an experimental investigation into the effectiveness of an
innovative hybrid control approach based on an intelligent active force control (IAFC) …
