我院刘恒教授在《IEEE Transactions on Neural Networks and Learning Systems》上发表学术论文

 

近日,我院刘恒教授以第一作者在人工智能及计算机领域国际顶级期刊《IEEE Transactions on Neural Networks and Learning Systems》上发表学术论文:Adaptive Neural Network Backstepping Control of Fractional-Order Nonlinear Systems With Actuator Faults, 31(12): 5166-5177, 2020. 该期刊为中科院一区TOP期刊,2020年影响因子为8.792

本文主要研究了分数阶不确定系统的容错控制问题。论文构造了一类新的分数阶滤波,使用反步控制的方法实现了分数阶系统的容错控制。

论文摘要:

Backstepping control for fractional-order nonlinear systems (FONSs) requires the analytic calculation of fractional derivatives of certain complicated stabilizing functions, which becomes prohibitive as the order of the system increases. This article aims to facilitate the adaptive neural network (NN) backstepping control design for FONSs with actuator faults whose parameters and patterns are fully unknown. A fractional filtering approach, which obviates the requirement of analytic fractional differentiation, is used to generate command signals together with their fractional derivatives. Compensated tracking errors that can eliminate approximation errors of command signals are generated by fractional filters. The proposed adaptive NN command filtered backstepping control (ANNCFBC) approach, together with fractional adaptive laws, guarantees not only the boundedness of all involved variables but also the convergence of both the tracking error and the compensated tracking error to a sufficiently small region. Finally, simulation studies are given to indicate the effectiveness of the proposed control method.
