Tracking control for nonlinear systems with time-varying delay using the fuzzy preview repetitive control approach
This paper investigates an innovative technology for fuzzy preview repetitive control (FPRC) in nonlinear systems with time-varying delay and uncertainties using the Takagi-Sugeno (T-S) fuzzy model. The proposed FPRC strategy considers time-changing delays and previewable, periodic target signals. The controller integrates a fuzzy output feedback controller, a fuzzy preview controller, and a repetitive controller to address the tracking control problem of periodic target signals. The research constructs a T-S fuzzy augmented error system using the error system method and state augmentation technique. Subsequetnly, the FPRC design challenge is transformed into a feedback stabilization problem of the augmented error system. Empolying fuzzy Lyapunov function and linear matrix inequality (LMI) techniques, the study derives sufficient conditions for the asymptotic stability of the augmented error system in the form of a set of LMIs, presenting the design method of the FPRC law. The validity of the results is demonstrated through numerical simulations.
期刊介绍:
Since its launching in 1978, the journal Fuzzy Sets and Systems has been devoted to the international advancement of the theory and application of fuzzy sets and systems. The theory of fuzzy sets now encompasses a well organized corpus of basic notions including (and not restricted to) aggregation operations, a generalized theory of relations, specific measures of information content, a calculus of fuzzy numbers. Fuzzy sets are also the cornerstone of a non-additive uncertainty theory, namely possibility theory, and of a versatile tool for both linguistic and numerical modeling: fuzzy rule-based systems. Numerous works now combine fuzzy concepts with other scientific disciplines as well as modern technologies.
In mathematics fuzzy sets have triggered new research topics in connection with category theory, topology, algebra, analysis. Fuzzy sets are also part of a recent trend in the study of generalized measures and integrals, and are combined with statistical methods. Furthermore, fuzzy sets have strong logical underpinnings in the tradition of many-valued logics.
