Bistable states of thermal convectional flow in porous media .

多孔介质中的双稳热对流。

An unmanned aerial vehicle uses a backstepping flight control law in order to bestow good flying qualities for flight conditions . In comparison with convectional control methods , the backstepping controller is much simpler and easier to construct and implement .

无人飞行载具使用倒逆步飞行控制定律来维持良好的飞行姿态,比起传统控制法则,倒逆步控制器更容易且简单地实现。
