This paper proposed a new method for scheduling periodic and aperiodic tasks in the hard real-time environment.The method advanced virtual deadline and virtual period for aperiodic tasks,then implemented the designment of task priority based on multi-feature parameters.This overcomed the insufficient of scheduling methods that considered single-feature parameter or ignored aperiodic task's own parameters,also enhanced the aperiodic tasks' response speed and the scheduling performance.The result of experiment based on RT-Linux environment of unmanned airship's autopilot shows that the new method is schedulable.
