The necessary and sufficient conditions for the linearization of the nonlinear control systems via restricted dynamic feed back have been found. These require checking with almost all indices from 0 to 2n-3. In this paper, we exploit the inherent structure of the system and find an efficient method to find linearizability of the system by reducing the range of the index to check. Our examples show the efficiency of our method.

In this paper, a formation guidance method for UAVs (Unmanned Aerial Vehicles) to simulate the formation flight of birds proposed. The proposed method solves all issues of approaching for formation, formation keeping, and scarce chance to be collided with each UAV during formation process. Also, we design the feedforward controller to compensate the change of speed and heading for maneuvering of the leader UAV and the feedback controller to consider the response lag of the system. The stability and performance of the proposed controller is verified via numerical simulations of the full 6-Dof model of UAV.
