Considering the problem of tracking control for a quadrotor unmanned aerial vehicle (QUAV) with input saturation, parameter uncertainties and external disturbances, command filtered backstepping-based fixed-time adaptive scheme was developed. The “explosion complexity” (EOC) is tackled by utilizing filter, influence error removed based on fractional power-error-compensation mechanism. A auxilia...

Abstract This paper proposes an adaptive control method for underactuated complex nonlinear system, that is, unmanned aerial vehicle (UAV), to realize high‐precision trajectory tracking under input saturation constraint and other disturbances via artificial neural network anti‐saturation auxiliary system. First, the rigid body motion theory is applied establish a simplified dynamic model of UAV...

This article addresses the cooperative fault-tolerant control problem for networks of stochastic nonlinear systems with actuator faults and input saturation. The fuzzy neural (FNNs) are employed to estimate unknown functions disturbance terms. To analyze nondifferential saturation nonlinearity, a smooth function signal is constructed function. A novel adaptive protocol proposed by using backste...

Many adaptive routing algorithms have been proposed for wormhole-routed interconnection networks. Comparatively little work, however, has been done on determining how the selection function affects the performance of an adaptive routing algorithm. In this paper, we present a detailed simulation study of various selection functions for four different fully adaptive wormhole routing algorithms fo...

Traditional adaptive control lacks rigorous theoretical treatment for control in the presence of actuator saturation. Generally, adaptation is stopped as soon as the control saturates to avoid incorrect adaptation. Adaptation in the presence of saturation may be critical, especially when the controller is recovering from a failure. This paper presents an Adaptive Control methodology that facili...

Observer based stochastic disturbance accommodating control scheme utilizes an estimator to determine the necessary corrections to the nominal control input and thus minimizes the adverse effects of both model uncertainties and external disturbances on the controlled system. The total control input, which includes the nominal control as well as the control corrections to the nominal control to ...
