Abstract: | With the digital development of aviation and aerospace,1553B bus is widely used in control system.For the demands of reliability and safety for the launch and control system,aiming at a self-determination variable structure bus controller,an embedded redundancy management method is designed and realized based on synchronization,data across chain communication and reconstruction technology.The bus system is reconfigured independently when a recoverable failure happened.Finally,experimental results show that the software method is reliable and stable,which can meet the needs of engineering application,and has broad application prospects. |
