Passivity of switched hopfield neural networks without online learning

As a continuation of our previous published results, in this study, we propose some results on passivity of switched Hopfield neural networks without online learning. First, a new matrix norm based condition for passivity of switched Hopfield neural networks is proposed. Second, a new passivity condition in the form of Linear Matrix Inequality (LMI) for switched Hopfield neural networks is proposed. In contrast to the existing result, the proposed conditions ensure asymptotic stability, but also passivity from the external input vector to the output vector without online learning.
