A Kind of Discrete Variable Structure UCAV Guidance Law Restrict by the Entering Angle

To solve the problem that the UCAV load data link make analog signals guidance law cannot be used directly, a kind of new discrete variable structure guidance law arithmetic is brought out, which takes the restriction of entry angle into consideration, and conquers the buffeting phenomenon when the tradition discrete variable structure control arithmetic get into sliding mode. The simulation results show that the discrete signal guidance law can meet the tactical UCAV indicator.
