The study of UCAV layered variable structure flight control arithmetic

To solve the question that the UCAV independent flight, a kind of layered fight control arithmetic, based on discrete variable structure control, is brought out. The arithmetic uses a kind of guidance law bring the contrail which should be flight. The guidance law is based on variable structure control and restrict by enter angle. And then make discrete mode on airplane and trace point, compute the control element of flight control. The arithmetic has realized the UCAV independent flight. The simulation results show that the discrete layered variable structure flight control arithmetic meet the tactical guide line of UCAV.
