| Abstract: | A real-time,deterministic and synchronized network is required for the shipboard dynamical control system.To establish a real-time and easy-to-use networked control system with short packets and low overloads,a reduced NTP-based technology is developed to perform network time synchronization.Experimental result reveals that it can meet the demands of shipboard dynamical networked control system and the synchronization granularity is millisecond. |
