The invention discloses a micro unmanned aerial vehicle applying a grid rudder and a control method, and belongs to the field of attitude control of micro aircrafts. The unmanned aerial vehicle adopts a cylindrical shell, four grid rudder surfaces are uniformly distributed at the bottom of the cylindrical unmanned aerial vehicle shell in a horizontal installation mode, the symmetric center of the four grid rudder surfaces and the gravity center of the unmanned aerial vehicle are located on the same vertical line, a propeller of the unmanned aerial vehicle is located above the top of the cylindrical unmanned aerial vehicle shell, and the grid rudder surfaces are installed at the bottom of the unmanned aerial vehicle and used for attitude control of the unmanned aerial vehicle. Compared with a single-plate rudder surface on a conventional small unmanned aerial vehicle, the grid rudder surface has more excellent aerodynamic characteristics, has more excellent control performance when being applied to the small unmanned aerial vehicle, and can effectively reduce the influence of crosswind. Through numerical simulation, flight tests are respectively carried out in windless and windy environments, and simulation calculation and test results both verify that the aerodynamic characteristics and the control performance of the grid rudder surface are better than those of the conventional single-plate rudder surface.
