Intelligent plug-and-play aircraft electrical system reconfiguration method

Provided is an intelligent plug-and-play aircraft electrical system reconfiguration method. A main control module, function modules and spare modules of the function modules are connected by plug-and-play standard interfaces to form an aircraft reconfigurable electrical system. The main control module selects needed function modules according to a task executed by a spacecraft through an intelligent algorithm, activates the function modules according to a reconfigurable algorithm to form an electrical system for executing the corresponding task, checks the function modules of the electrical system through a fault diagnosis algorithm, isolates a function module and activates the spare module thereof when the function module fails, and reconstructs the electrical system for executing the task to complete the task. By adopting the method, the multi-task input requirement of spacecrafts can be satisfied effectively, and the task execution cost of spacecrafts can be reduced.
