Abstract
It is known that gradient information plays an essential role in GNS (gradient neurodynamic system) for finding the solution to static problems, and derivative information plays an essential role in ZNS (zeroing neurodynamic system) for finding the solution to temporally-variant problems. This fact prompts us to search for a way to simultaneously utilize them for better performance. Motivated by this point, a novel finite-time convergent GAGZNS (gradient-activation gradient-zeroing neurodynamic system) is designed and proposed to online solve temporally-variant LSE (linear simultaneous equation). The proposed GAGZNS utilizes both gradient information and derivative information, and thus can materialize a faster FTC (finite-time convergence) as compared with the ZNS. The property of FTC and the corresponding upper bound of convergence time are derived through strict theoretical proof and verified through two simulation examples. Finally, on the basis of the AoA (angle-of-arrival) technology, we conduct another example of mobile object localization to exhibit the practicality of the proposed GAGZNS.
