Abstract: | This paper discusses the global-μ stability problem of quaternion-valued neutral neural networks(QVNTNN) with time delay. Firstly, in order to reduce the computational complexity caused by the non-commutability of quaternion matrix multiplication, the QVNTNN system is converted into two complex-valued systems by using the complex decomposition method. Secondly, the existence and uniqueness of the solution of the QVNTNN system with time-delay is proved by the theory of homeomorphism mapping. Then, a new Lyapunov functional is constructed by using the system information, and the inequality is scaled by the inequality technique and the free weight matrix. It has obtained the global-μ stability criterion for the QVNTNN system with time-delay. Finally, a numerical example is given to verify the validity of the method and the correctness of the conclusion. |
