The formation of UAVs is studied by introducing game theory into distributed control,and a game-based distributed algorithm is developed.The algorithm combines the gradient descent and consensus to convert formation of UAVs into a problem of distributed game.The consensus technique is adopted to guarantee the estimation of the positions of all UAVs,and gradient descent is for the Nash equipment.By the proposed algorithm,UAVs can complete any formation even each UAV only have the neighbor UAV's information not all UAVs'.The simulation result verifies the effectiveness of the proposed algorithm.

Aiming at the complex technology, long development cycle and high cost of large satellites, under the background for satellite emergency launch and rapid networking, the way of reconstruction of missiles and installing a small satellite to achieve the small satellite's mobile launch into orbit is presented. On the basis of missile dynamics model, the maneuvering optimization model for missile carried satellite is established; a small satellite launch program is designed. The genetic algorithm is used to solve the missile launch model. Simulation results show that a small satellite's mobile launch can be achieved by the modification of the missile.
