Improved Extended Dissipativity Results for T-S Fuzzy Generalized Neural Networks With Mixed Interval Time-Varying Delays

Abstract

The asymptotic stability and extended dissipativity performance of T-S fuzzy generalized neural networks (GNNs) with mixed interval time-varying delays are investigated in this paper. It is noted that this is the first time that extended dissipativity performance in the T-S fuzzy GNNs has been studied. To obtain the improved results, we construct the Lyapunov-Krasovskii functional (LKF), which consists of single, double, triple, and quadruple integral terms containing full information of the delays and a state variable. Moreover, an improved Wirtinger inequality, a new triple integral inequality, and zero equation, along with a convex combination approach, are used to deal with the derivative of the LKF. By using Matlab's LMI toolbox and the above methods, the new asymptotic stability and extended dissipativity conditions are gained in the form of linear matrix inequalities (LMIs), which include passivity, L 2 − L ∞ , H ∞ , and dissipativity performance. Finally, numerical examples that are less conservative than previous results are presented. Furthermore, we give numerical examples to demonstrate the correctness and efficacy of the proposed method for asymptotic stability and extended dissipativity performance of the T-S fuzzy GNNs, including a particular case of the T-S fuzzy GNNs.

Robust Mixed Performance Control of Uncertain T-S Fuzzy Systems With Interval Time-Varying Delay by Sampled-Data Input

“…In this paper, we consider interval time-varying delay and interval sampling period instead of constant delay and pointwise sampling period in [20], respectively. Furthermore, some interesting research topics for T-S fuzzy systems can be investigated, e.g., asynchronous non-PDC controller and quantizer [32], [33], dissipativity and dissipative control [15], [16], event-triggered control [33], [34], finitetime control [27]- [32], nonfragile control [14], passivity and VOLUME 10, 2022…”

Fractional Order Nonlinear Bone Remodeling Dynamics Using the Supervised Neural Network

“…The numerical studies of the fractional MBD model based on the bone remodeling with the tumor effects (1) have been provided in the current study by using the artificial intelligence (AI) together with the configuration of LVMBPNN [34][35][36][37][38][39][40][41]. Furthermore, the fractional MBD model has been designed to present the analysis of super slow evolvement and superfast progressions by substituting the ordinary integer order derivation in the set of Eq.…”

An Artificial Approach for the Fractional Order Rape and Its Control Model

“…The stochastic computing performances through the ANNs based on the local and global operators have been implemented to solve several nonlinear, stiff, complex, and singular models [31][32][33][34][35][36][37][38][39][40][41][42][43]. Recently, these applications have been used to solve the Lane-Emden nonlinear system [44], functional order system [45], singular form of the fractional order equations [46][47][48], periodic differential system [49], delayed differential systems [50] and HIV infection based mathematical models [51,52].…”
