In order to overcome the problems existing in the traditional design method of micro air vehicles (MAVs), such as long period, high cost and low efficiency, a design environment of virtual prototype of the flight control system (FCS-VP) is constructed. In this environment, the FCS-VP of a MAV, which is in a hybrid three-layer structure consisting of a task-scheduling layer, an action-planning layer and a basic regulation layer, is designed with SysML and Simulink. Simulation results demonstrate that the designed FCS-VP well simulates the FCS of MAV in terms of structure, function, behavior and...
