Research on autonomous docking control strategy for soft aerial refuelling

In this paper the autonomous capture control was researched. The conditions of capture, criterion of success, arrangeme nt of the autonomous capture were analyzed. On this basis, three capture models were introduced, namely tracking model, statistics mid-value tracking model, and best chance trajectory model. Dynamic control models were constructed of autonomous capture system. Under the influence of air disturbance and tanker wake, Dynamic simulation of the autonomous capture control and the disturbance response was researched, results show that, receiver aircraft can't follow and engage the drogue, because of its relatively low nature frequency. When considering the best chance trajectory method, based on offsetting the aim point and good control of the speed, capture can be achieved.
