Optimal Path Planning and Tracking Control Methods for Parafoil

Due to the problems of flexible parafoil systems that are susceptible complex disturbances, such as external wind fields and being difficult control, it is necessary study path planning tracking control methods under conditions. In this paper, particle model dynamic system established, method based on original natural (ON) principle coupled with meteorological interference, terrain avoidance, other environmental models studied. Sliding mode introduced into system, errors position velocity taken design criteria for sliding surface. The law controller derived. Through simulation comparison methods, designed in paper can reflect better performance. effectively suppress impact improve accuracy, enhance robustness.
