In this paper, a protocol-based finite-horizon H and l-l estimation approach is put forward to solve the state estimation problem for discrete-time memristive neural networks (MNNs) subject to time-varying delays and energy-bounded disturbances. The Round-Robin protocol is utilized to mitigate unnecessary network congestion occurring in the sensor-to-estimator communication channel. For the delayed MNNs, our aim is to devise an estimator that not only ensures a prescribed disturbance attenuation level over a finite time-horizon, but also keeps the peak value of the estimation error within a given range. By resorting to the Lyapunov-Krasovskii functional method, the delay-dependent criteria are formulated that guarantee the existence of the desired estimator. Subsequently, the estimator gains are obtained via figuring out a bank of convex optimization problems. The validity of our estimator is finally shown via a numerical example.
本文提出了一种基于协议的有限时域 H 和 l-l 估计方法,用于解决时变时滞和能量有界干扰下离散时间忆阻神经网络(MNN)的状态估计问题。采用轮询协议来减轻传感器到估计器通信通道中不必要的网络拥塞。对于时滞 MNN,我们的目标是设计一个估计器,不仅可以在有限的时域内确保规定的干扰衰减水平,还可以将估计误差的峰值保持在给定范围内。通过利用 Lyapunov-Krasovskii 泛函方法,制定了与时滞相关的准则,以保证期望估计器的存在。随后,通过求解一组凸优化问题获得了估计器增益。最后,通过数值示例验证了我们的估计器的有效性。
