摘要：
A novel complex varying-parameter finite-time zeroing neural network (VPFTZNN) for finding a solution to the time-dependent division problem is introduced. A comparative study in relation to the zeroing neural network (ZNN) and finite-time zeroing neural network (FTZNN) is established in terms of the error function and the convergence speed. The error graphs of the VPFTZNN design show promising results and perform better than corresponding ZNN and FTZNN graphs. The proposed dynamical systems are suitable tools for overcoming the division by zero difficulty, which appears in the time-varying division. An application of the introduced VPFTZNN model in an output tracking control time-varying linear system is demonstrated.
