Control law for a missile intercept system
Abstract
A feedback control law is derived for a two dimensional missile intercept system which combines in a step-by-step manner the closed form solutions to a least squares estimation of the target turn rate, line speed and heading with a minimum control energy problem subject to a terminal intercept constraint. The major assumptions are that the pursuer possesses thrust modulation capabilities, in addition to thrust vectoring, and that continuous measurements of the range coordinates are available for estimation purposes. Simulation results are included which indicate that good terminal accuracy is achieved when the estimation errors are small and illustrate the limitations on accuracy when fluctuations occur in the target speed and turn rate.
