In this paper, we develop a new guidance law to address the problem of a single unmanned aerial vehicle (UAV) circling a stationary target in an arbitrarily specified plane in three dimensions. With the assumption of constant velocity, the proposed guidance law generates only lateral acceleration command to control the UAV. The guidance command contains two terms, the enclosing term and the plane pursuit term. The enclosing term can be obtained by applying a two dimensional enclosing guidance law in the plane defined by the UAV’s line-of-sight vector and the velocity vector. By this method, the two-dimensional guidance law is extended to three dimensions. The plane pursuit term is generated based on the error between the desired plane’s normal vector and the UAV’s velocity vector, and enables the UAV to arrive at the desired pursuit plane within the predefined time. In addition, we theoretically analyze and prove the stability of proposed guidance law. Finally, we conduct the numerical simulations to illustrate that the method proposed is effective.
