This study introduces robust control for memristive neural networks (MNNs) with time-varying delays. It ensures stability using novel Lyapunov-based methods and linear matrix inequalities for controller design.
Area of Science:
- Control Theory
- Neural Networks
- Nonlinear Systems
Background:
- Memristive neural networks (MNNs) are crucial for complex computations.
- Time-varying delays in MNNs introduce stability challenges.
- Robust control is essential for reliable MNN performance.
Purpose of the Study:
- To design an output-feedback controller for MNNs with non-differentiable time-varying delays.
- To ensure the $\mathcal{L}_2 -\mathcal{L}_{\infty}$ stability of the MNN system.
- To develop a systematic design method for the controller.
Main Methods:
- Utilizing a Lyapunov functional for stability analysis.
- Applying the Bessel-Legendre inequality and convex combination inequality.
- Employing linear matrix inequalities (LMIs) for controller synthesis.
- Decoupling nonlinear terms within the MNN dynamics.
Main Results:
- A novel criterion for $\mathcal{L}_2 -\mathcal{L}_{\infty}$ stability of MNNs with delays is established.
- A concrete LMI-based design scheme for the output-feedback controller is presented.
- The proposed methods are validated through two illustrative examples.
Conclusions:

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
