This paper presents a distributed integrated fault diagnosis and accommodation scheme for leader‐following formation control of a class of nonlinear uncertain second‐order multi‐agent systems. The fault model under consideration includes both process and actuator faults, which may evolve abruptly or incipiently. The time‐varying leader communicates with a small subset of follower agents, and each...
This paper presents a nonlinear adaptive fault-tolerant control algorithm for accommodating actuator faults in quadrotor UAVs and an online controller integrity method for assuring safety of adaptive control system in the presence of controller software faults. The actuator faults considered in this paper are modeled as partial losses of effectiveness in one of the rotors. Using adaptive backstepping...
This paper presents the design, development and implementation of an automation system of batch process suitable for vulcanization accelerator production applications. The unique feature of the accelerator production process is that it has complex nonlinear, time-varying and large time-delay characteristics. Based on its kinetics characteristics and technical analysis of the batch process, adaptive...
This paper presents an integrated fault diagnosis and fault-tolerant control methodology for a two-link planar nonlinear robotic systems. Based on the information obtained during a fault diagnostic procedure, a fault-tolerant control component is designed to compensate for the effect of faults using an adaptive learning structure in the form of Takagi-Sugeno fuzzy systems. First, a baseline controller...
This paper presents an integrated fault diagnosis and fault-tolerant control methodology for a class of nonlinear MIMO systems. Based on the fault information obtained during the diagnostic procedure, a fault-tolerant control component is designed to compensate for the effect of faults. In the presence of a fault, a baseline controller guarantees the boundedness of all system signals until the fault...
This paper addressed the adaptive backstepping control of space flexible-joint manipulator with nonlinear friction compensation. LuGre dynamic friction model was adopted to characterize the friction forces and dual state observers were proposed to estimate the internal immeasurable state of LuGre model. Based on the estimated friction state, adaptive laws were designed to identify the unknown model...
This paper presents a novel intelligent hierarchical approach to automatically detecting, isolating, and accommodating faults in flight control systems. The proposed architecture has three main components. First, a new nonlinear fault diagnosis scheme is used to detect the occurrence of any faults and to determine the particular component that has failed. Second, a controller module consists of a...
