Model Predictive Control Research Based on Auto Landing System

Auto landing is a very complex stage of flight. Although percentage of auto landing to total flight is only 2~3%, about one third of flight accidents appear in this phase. Moreover half of flight accident of high speed jet-planes occur at this stage. In this paper, we discuss a kind of unmanned aerial vehicle which has a special figure and rigorous lateral requirements. Therefore this paper uses hierarchic control system which is made up of predictive controller plus traditional PID controller. The simulation results show MPC method can improve the landing precision efficiently; meanwhile control the roll angle rigorously.
