Several improvements of the Zhang neural network (ZNN) dynamics for solving the time varying matrix inversion problem are presented. Introduced ZNN dynamical design is termed as ZNN models of the order p, p >= 2, and it is based on the analogy between the proposed continuous-time dynamical systems and underlying discrete-time pth order hyperpower iterative methods for computing the constant matrix inverse. Such ZNN design is denoted by ZNN(H)(p). Particularly, the ZNN(H)(2) design coincides with the standard ZNN design. Moreover, ZNN(H)(3) design represents a time-varying generalization of the previously defined ZNNCM model. In addition, an integration-enhanced noise-handling ZNN(H)(p) model, termed as IENHZNN(H)(p) H, is introduced. In the time-invariant case, we present a hybrid enhancement of the ZNN(H)(p) model, shortly termed as HZNN(H)(p), and investigate it theoretically and numerically. Theoretical and numerical comparisons between the improved and standard ZNN dynamics are considered. Keywords Zeroing
